(a) Triangle
(b) Quadrilateral (c) Pentagon (d) Hexagon
(e) Heptagon
(1) Octagon (g) Nonagon
(h) Decagon
polygons in degrees and grades
Answers
(a) 120° or 133.33 grades.
(b)135° or 150 grades.
(c) 144° or 160 grades.
(d) 150° or 166.67 grades.
(e) 154.29° or 171.43 grades.
(f) 157.5° or 175 grades.
(g) 160° or 177.78 grades.
(h) 162° or 180 grades.
Step-by-step explanation:
A regular polygon is a polygon that has all sides and all angles equal.
Each interior angle, k (measured in degrees), of a regular polygon is given by;
k = s ÷ n -----------(k)
Where;
s = sum of the interior angle of the polygon.
n = number of sides of the polygon
To get s, we use
s = (n - 2) x 180 [This is the formula to calculate the sum of the interior angles of a polygon]
Substituting s this into equation (i) gives
k = (n - 2) x 180 ÷ n
k = 180(n - 2) ÷ n -------------(ii)
(a) Triangle.
A triangle has n = 3 sides, therefore, each interior angle of a triangle is found by substituting n = 3 into equation (ii)
k = 180(3 - 1) ÷ 3
k = 180(2) ÷ 3
k = 180 x 2 ÷ 3
k = 360 ÷ 3
k = 120°
Convert to grade.
Remember that;
90° = 100 grades
∴ 120° = [tex]\frac{120 * 100}{90}[/tex] grades
⇒ 120° = 133.33 grades.
Therefore, each interior angles of a regular triangle is 120° or 133.33 grades.
(b) Quadrilateral.
A quadrilateral has n = 4 sides, therefore, each interior angle of a quadrilateral is found by substituting n = 4 into equation (ii)
k = 180(4 - 1) ÷ 4
k = 180(3) ÷ 4
k = 180 x 3 ÷ 4
k = 540 ÷ 4
k = 135°
Convert to grade.
Remember that;
90° = 100 grades
∴ 135° = [tex]\frac{135 * 100}{90}[/tex] grades
⇒ 135° = 150 grades.
Therefore, each interior angles of a regular quadrilateral is 135° or 150 grades.
(c) Pentagon
A pentagon has n = 5 sides, therefore, each interior angle of a pentagon is found by substituting n = 5 into equation (ii)
k = 180(5 - 1) ÷ 5
k = 180(4) ÷ 5
k = 180 x 4 ÷ 5
k = 720 ÷ 5
k = 144°
Convert to grade.
Remember that;
90° = 100 grades
∴ 144° = [tex]\frac{144 * 100}{90}[/tex] grades
⇒ 144° = 160 grades.
Therefore, each interior angles of a regular pentagon is 144° or 160 grades.
(d) Hexagon
A hexagon has n = 6 sides, therefore, each interior angle of a hexagon is found by substituting n = 6 into equation (ii)
k = 180(6 - 1) ÷ 6
k = 180(5) ÷ 6
k = 180 x 5 ÷ 6
k = 900 ÷ 6
k = 150°
Convert to grade.
Remember that;
90° = 100 grades
∴ 150° = [tex]\frac{150 * 100}{90}[/tex] grades
⇒ 150° = 166.67 grades.
Therefore, each interior angles of a regular hexagon is 150° or 166.67 grades.
(e) Heptagon
A heptagon has n = 7 sides, therefore, each interior angle of a heptagon is found by substituting n = 7 into equation (ii)
k = 180(7 - 1) ÷ 7
k = 180(6) ÷ 7
k = 180 x 6 ÷ 7
k = 1080 ÷ 7
k = 154.29°
Convert to grade.
Remember that;
90° = 100 grades
∴ 154.29° = [tex]\frac{154.29 * 100}{90}[/tex] grades
⇒ 154.29° = 171.43 grades.
Therefore, each interior angles of a regular heptagon is 154.29° or 171.43 grades.
(f) Octagon
An octagon has n = 8 sides, therefore, each interior angle of a octagon is found by substituting n = 8 into equation (ii)
k = 180(8 - 1) ÷ 8
k = 180(7) ÷ 8
k = 180 x 7 ÷ 8
k = 1260 ÷ 8
k = 157.5°
Convert to grade.
Remember that;
90° = 100 grades
∴ 157.5° = [tex]\frac{157.5 * 100}{90}[/tex] grades
⇒ 157.5° = 175 grades.
Therefore, each interior angles of a regular octagon is 157.5° or 175 grades.
(g) Nonagon
A nonagon has n = 9 sides, therefore, each interior angle of a nonagon is found by substituting n = 9 into equation (ii)
k = 180(9 - 1) ÷ 9
k = 180(8) ÷ 9
k = 180 x 8 ÷ 9
k = 1440 ÷ 9
k = 160°
Convert to grade.
Remember that;
90° = 100 grades
∴ 160° = [tex]\frac{160 * 100}{90}[/tex] grades
⇒ 160° = 177.78 grades.
Therefore, each interior angles of a regular nonagon is 160° or 177.78 grades.
(h) Decagon
A decagon has n = 10 sides, therefore, each interior angle of a decagon is found by substituting n = 10 into equation (ii)
k = 180(10 - 1) ÷ 10
k = 180(9) ÷ 10
k = 180 x 9 ÷ 10
k = 1620 ÷ 10
k = 162°
Convert to grade.
Remember that;
90° = 100 grades
∴ 162° = [tex]\frac{162 * 100}{90}[/tex] grades
⇒ 162° = 180 grades.
Therefore, each interior angles of a regular decagon is 162° or 180 grades.

pls answer! Dylan spots an airplane on radar that is currently approaching in a straight line, and

Dylan initially measures an angle of elevation of 16° to the plane at point A. At some
later time, he measures an angle of elevation of 36° to the plane at point B. Find the
distance the plane traveled from point A to point B. Round your answer to the
nearest foot if necessary.
Answers
Answer:
13510 ft
Step-by-step explanation:
I have attached a triangle diagram to depict this situation.
From the diagram, we see that distance between A and B is denoted by x.
Now, from trigonometric ratios in this type of triangle, let's first find y.
6400/y = tan 36
y = 6400/tan 36
y = 8808.84 ft
Now, we can find x from;
6400/(8808.84 + x) = tan 16
6400/tan 16 = 8808.84 + x
22319.452 = 8808.84 + x
x = 22319.452 - 8808.84
x ≈ 13510 ft
The distance the plane traveled from point A to point B is 13510 ft
Calculation of the distance:Here we assume the distance between A and B should be x.
Now the y value should be
[tex]6400\div y = tan 36\\\\y = 6400\div tan 36[/tex]
y = 8808.84 ft
Now, we can find x
[tex]6400\div (8808.84 + x) = tan\ 16\\\\6400\div tan\ 16 = 8808.84 + x[/tex]
22319.452 = 8808.84 + x
x = 22319.452 - 8808.84
x ≈ 13510 ft

Rhode Island Red chicks cost $3.20 each and Buckeye chicks cost $3.44 each.
A farmer buys 4 Rhode Island Red chicks for every 3 Buckeye chicks.
He buys 70 chicks in all. What is the total cost of the farmer's chicks?
Show your work
Answers
Answer:
Step-by-step explanation:
Rhode Island Red chicks = 3.20 Dollars
Buckeye chicks = 3.44 Dollars
For every3 times as 3.44 Dollars, The farmer buys 4 times as 3.20 Dollars so simply Multiply until you reach 70 S0..
3.44 x 3
= 10.32
3.20 x 4
= 12.8
With 7 chicks, combine the prices of the chicks and multiply it by 10.
= 12.8 + 10.32
= 23.12
= 23.12 x 10
= 231.2
So 231.2 Dollars were spent for 70 chicks`in total.
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The total cost of farmers' chicks is $231.2
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x = 5 is an equation.
We have,
Total chicks = 70
4 Rhode Island Red chicks = 3 Buckeye chicks.
Multiply 10 on both sides.
40 Rhode Island Red chicks = 30 Buckeye chicks.
We see that,
40 + 30 = 70
Now,
Rhode Island Red chicks cost = $3.20
Buckeye chicks cost = $3.44
Now,
= 40 x 3.20 + 30 x 3.44
= 128 + 103.2
= $231.2
Thus,
The total cost of farmers' chicks is $231.2

A ball thrown in the air has a height of y = - 16x² + 50x + 3 feet after x seconds. a) What are the units of measurement for the rate of change of y? b) Find the rate of change of y between x = 0 and x = 2?
Answers
(a) ft/s
(b) 1ft/s
Step-by-step explanation:Given equation;
y = (- 16x² + 50x + 3)ft -------------(i)
Where;
y is measured in feet(ft)
x is measured in seconds(s).
(a) The rate of change of y with respect to x is found by dividing the total change in y by the total change in x. i.e
Δy / Δx
Where;
Δy = y₂ - y₁
Δx = x₂ - x₁
∴ Δy / Δx = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex] --------------(ii)
Since y is measured in feet, Δy will also be measured in feet.
Also, since x is measured in seconds, Δx will also be measured in seconds.
Therefore, the rate of change of y with respect to x (Δy / Δx) will be measured in feet per second (ft/s)
(b) The rate of change of y between x = 0 and x = 2 can be found by using equation (ii)
Where;
y₂ is the value of y at x = 2 found by substituting x = 2 into equation (i)
y₁ is the value of y at x = 0 found by substituting x = 0 into equation (i)
=> y₂ = - 16(2)² + 50(2) + 3 = 39
=> y₁ = - 16(1)² + 50(1) + 3 = 37
Now, substitute the values of y₂, y₁, x₂ and x₁ into equation (ii)
Δy / Δx = [tex]\frac{39 - 37}{2 - 0}[/tex]
Δy / Δx = [tex]\frac{2}{2}[/tex]
Δy / Δx = 1
Therefore, the rate of change of y is 1 ft/s

Drag the endpoints of the segment below to graph y = h-'(x).
Answers
Answer:
[tex]h^{-1}(x) = \frac{4}{3}x + \frac{23}{3}[/tex]
Step-by-step explanation:
Given
Graph h:
[tex](x_1,y_1) = (1,-5)[/tex]
[tex](x_2,y_2) = (9,1)[/tex]
Required
Plot [tex]h^{-1}(x)[/tex]
First, calculate h(x)
Calculate slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{1--5}{9-1}[/tex]
[tex]m = \frac{6}{8}[/tex]
[tex]m = \frac{3}{4}[/tex]
The equation is:
[tex]y = m(x - x_1) + y_1[/tex]
So, we have:
[tex]y = \frac{3}{4}(x - 1) -5[/tex]
[tex]y = \frac{3}{4}x - \frac{3}{4} -5[/tex]
[tex]y = \frac{3}{4}x + \frac{-3 - 20}{4}[/tex]
[tex]y = \frac{3}{4}x - \frac{23}{4}[/tex]
Next, calculate [tex]h^{-1}(x)[/tex]
Swap y and x
[tex]x = \frac{3}{4}y - \frac{23}{4}[/tex]
Solve for y
[tex]\frac{3}{4}y = x + \frac{23}{4}[/tex]
Multiply through by 4
[tex]3y = 4x + 23[/tex]
Divide through by 3
[tex]y = \frac{4}{3}x + \frac{23}{3}[/tex]
Replace y with [tex]h^{-1}(x)[/tex]
[tex]h^{-1}(x) = \frac{4}{3}x + \frac{23}{3}[/tex]

Two cards are drawn without replacement from a standard deck of 52 playing cards. What is the probability of choosing a king and then, without replacement, a face card? Express your answer as a fraction or a decimal number rounded to four decimal places
Answers
Answer:
0.0181 probability of choosing a king and then, without replacement, a face card.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Probability of choosing a king:
There are four kings on a standard deck of 52 cards, so:
[tex]P(A) = \frac{4}{52} = \frac{1}{13}[/tex]
Probability of choosing a face card, considering the previous card was a king.
12 face cards out of 51. So
[tex]P(B|A) = \frac{12}{51}[/tex]
What is the probability of choosing a king and then, without replacement, a face card?
[tex]P(A \cap B) = P(A)P(B|A) = \frac{1}{13} \times \frac{12}{51} = \frac{1*12}{13*51} = 0.0181[/tex]
0.0181 probability of choosing a king and then, without replacement, a face card.

A wet bicycle tire leaves a trace of water on the floor. The tire has a radius of 30 cm, and the bicycle wheel
makes 3 full rotations before stopping.
How long is the trace of water left on the floor?
Round your answer to the nearest cm.
Answers
Answer:
The trace of the water left on the floor is 566 cm.
Step-by-step explanation:
The bicycle wheel has a circular shape, therefore;
1 revolution is the same as the circumference of the wheel. So that 3 revolutions is the same as multiplying the circumference of the wheel by 3.
circumference = 2[tex]\pi[/tex]r
where r is the radius of the wheel (r = 30 cm).
Thus,
circumference = 2 x [tex]\frac{22}{7}[/tex] x 30
= [tex]\frac{1320}{7}[/tex]
circumference = 188.57 cm
3 revolutions = 3 x 188.57
= 565.71 cm
Therefore, the trace of the water left on the floor is 566 cm.
