Answer:
D. ∠3 and ∠4 are supplementary angles
Step-by-step explanation:
Supplementary angles are two angles that add up to 180°
∠3=15° ∠4=29°
15° + 29° = 180°
So, ∠3 and ∠4 are suplementary angles.

Given the following information, is it possible to determine the length of YZ? If so, find the length and explain below. If not, explain why not. Triangle ABC=XYZ, AB=3.7, AC=4.5
Answers
Answer:
YZ cannot be determined from the similar triangles
Step-by-step explanation:
Given two similar triangles, to get any sides of the triangles, the ratio of their congruent sides is equal to a constant, Hence;
AB/XY = AC/XY
Also, BC/YZ = AB/XY
This shows that to get YZ, both BC and XY must be given. Since we are not given either of the two sides hence YZ cannot be determined from the similar triangles

Calculate the length of AC, to the nearest tenth of a centimeter.
Answers
Answer:
AC ≈ 11.0 cm
Step-by-step explanation:
Using Pythagoras' identity in Δ CDE and Δ ADE
CE² + DE² = DC²
CE² + 7² = 8²
CE² + 49 = 64 ( subtract 49 from both sides )
CE² = 15 ( take the square root of both sides )
CE = [tex]\sqrt{15}[/tex]
-------------------------------------------------------
AE² + DE² = DA²
AE² + 7² = 10²
AE² + 49 = 100 ( subtract 49 from both sides )
AE² = 51 ( take the square root of both sides )
AE = [tex]\sqrt{51}[/tex]
Then
AC = AE + CE = [tex]\sqrt{15}[/tex] + [tex]\sqrt{51}[/tex] ≈ 11.0 cm ( to the nearest tenth )

Answers
Answer:
A. 5 × ( 3 + 2 + 2 1/4 )
Step-by-step explanation:
Hayden rode his bike 5 times. Each time, he biked a 3-mile path, a 2-mile path, and a 2 1/4 -mile path.
The expression represents the total number of miles he biked is calculated as:
The number of times he rode his bike × (sum of the number of miles he biked)
= 5 × ( 3 mile + 2 miles + 2 1/4 miles)
= 5 × (3 + 2 + 2 1/4)
Therefore, Option A is the correct option

explanation: the easiest way is to separate one of the diagonals into a triangle and use the pythagorean theorem.
a^2 + b^2 = c^2
4^2 + 3^3 = c^2
16 + 9 = c^2
25 = c^2
5 = c
you now know that both of the diagonals have a length of 5.
by counting the units on the two straight, you know that their length is 6.
6 + 6 + 5 + 5 = 22

Answer:
C
Step-by-step explanation:
We assume you want these in order by angle measure in some consistent units. Degrees is a reasonable unit to use here.
π radians = 180°
Substituting 180° where you see π, you find the angle values to be ...
2π = 2(180°) = 360°
7π/6 = 7/6(180°) = 210°
π/4 = (1/4)(180°) = 45°
Then the angles from least to greatest are ...
38°, 45°, 80°, 210°, 360°
or
38°, π/4, 80°, 7π/6, 2π . . . . matches the third choice
The area of a circle is 4π ft². What is the circumference, in feet? Express your answer in terms of \piπ.
Answers
Answer:
C = 4 pi ft
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
Solving for r
4 pi = pi r^2
Dividing each side by pi
4 = r^2
Taking the square root of each side
sqrt(4) = sqrt(r^2)
2 = r
Now we can find the circumference
C = 2 * pi *r
C = 2*pi*2
C = 4 pi ft

Explanation:
If you apply the distance formula, you should find that triangle DEF has the following side lengths
DE = 5EF = 5FD = sqrt(50)Those distances are exact. The sqrt(50) approximates to 7.071
Since 7.071 is the longest side, we'll make c = sqrt(50)
Then we have a = 5 and b = 5
Note that a^2+b^2 = 5^2+5^2 = 50 while c^2 = (sqrt(50))^2 = 50
Both a^2+b^2 and c^2 are equal to 50.
That means a^2+b^2 = c^2 is a true equation for the a,b,c values mentioned.
By the converse of the pythagorean theorem, we have shown that triangle DEF is a right triangle.
---------------
Side notes:
Triangle DEF is also isosceles because a = b = 5.If a^2+b^2 > c^2, then the triangle is acuteIf a^2+b^2 < c^2, then the triangle is obtuseIf a = b = c, then we have an equiangular triangleAnswer:

We know these triangles are congruent by looking at the information given. The bottom sides have the same lengths, giving us one part of SAS.
We can also see an a right angle is given to us at the bottom, this automatically means the left angle is also a right angle. This is the angle of SAS.
Lastly, we know they share another side because they’re sharing the same side exactly.

Answers
Answer:
4(19x + 42n + 15)
Step-by-step explanation:
Devi bought 7 skirts at $x each, n skirts at $12 each, (2n + 1) skirts at $15 each and 4 skirts at $3x each. Find the total cost of the skirts she bought.
total cost of the skirt bought can be determined by adding the total costs of each shirt bought
7 skirts at $x each = $7x
n skirts at $12 each = $12n
(2n + 1) skirts at $15 = (2n + 1) x 15 = 30n + 15
4 skirts at $3x each = $12x
7x + 12n + 30n + 15 + 12x
combine like terms
19x + 42n + 15
