Answer:
35
Step-by-step explanation:
Cause they both add up to a right angle which is 90 degrees. so 90-55=35
∠angle, a and ∠angle, b are complementary angles. ∠ an ∠angle, a measures 5 5 ∘ 55 ∘ 55, degrees. so we can conclude that ∠b = 35.
What is the angle sum property?The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.
∠angle, a and ∠angle, b are complementary angles.
∠ an ∠angle, a measures 5 5 ∘ 55 ∘ 55, degrees.
we want to measure ∠ b
We know that the sum of Complementary angles is equal to 90 degrees.
so to find the measure of angle B we subtract the given angle from 90
∠ b + ∠ a = 90
∠ b + 55 = 90
∠ b = 90-55
∠ b =35
so we can conclude that ∠b = 35.

In the later afternoon on a sunny day, Shanice goes outside with a tape measure. She first measures her shadow which is 7 feet 6 inches long. She then measures the shadow of the oak tree in the back yard which is a whopping 74 feet 3 inches. Not content to stop there, she also measures the shadow of her house (taking the longest measurement possible) and finds that it is 28 feet 6 inches. Using this information, find out how much taller the tree is than the house if Shanice's actual height is 5 feet 10 inches.
Answer:
29 feets 3 inches
Step-by-step explanation:
We need to obtain the actual height of oak tree :
Converting measurement to inches :.
1 Feet = 12 inches
Shanice height, SA = 5ft 10 in = (12*5 + 10) = 70 in
Shanice shadow, SS = 7ft 6in = (12*7 + 6) = 90 in
Tree shadow, TS = 74ft 3 in =(12*74 + 3) = 891 in
Let actual tree height = TH
Using the relation :
SA / SS = TH / TS
70 / 90 = TH / 891
Cross multiply :
90 * TH = 891 * 70
TH = (891 * 70) / 90
TH = 693 inches
Height of house = 28ft 6 in = (28*12 + 6) = 342 in
Height difference :
(693 - 342) in = 351 inches
351 in / 12 = 29 feets 3 inches

Which of the following accurately compares 15 - v105 and 5?
PLEASE HELP ME
Answer:
[tex]\sqrt{105}[/tex] is slightly more than 10, so 15 - [tex]\sqrt{105}[/tex] is less than 5.
Step-by-step explanation:
Given expression is (15 - √105).
Since, √105 ≈ Slightly greater than 10 [Since, [tex]\sqrt{100}=10[/tex]]
Therefore, when we subtract the value of [tex]\sqrt{105}[/tex] from 15,
15 - [tex]\sqrt{105}[/tex] = Slightly less than 5
From the given options answer will be,
[tex]\sqrt{105}[/tex] is slightly more than 10, so 15 - [tex]\sqrt{105}[/tex] is less than 5.

If the supplement of an angle is 4 times of its compliment, find the angle.
PLSSSSSSSSSSS HELP ASAP
Answer:
The angle is 60°
Step-by-step explanation:
A supplement angle is the angle whose sum is equal to 180°.
The supplement angle = 180° - x
A complement angle is the angle whose sum is equal to 90°.
The complement angle = 90° - x
Given,
supplement angle = 4 × complement angle
(180° - x) = 4 × (90° - x)
180° - x = 360° - 4x
4x - x = 360° - 180°
3x = 180°
x = 60°
The supplement angle = 180° - x
⇒ 180° - 60°
⇒ 120°
The complement angle = 90° - x
⇒ 90° - 60°
⇒ 30°
Answer:
The angle is 60 degrees.
Step-by-step explanation:
Let the angle be x.
Then its supplement = 180-x.
Its complement = 90-x, so we have the equation:
180 - x = 4(90 - x)
180 - x = 360 - 4x
-x + 4x = 360 - 180
3x = 180
x= 60 degrees.

Can I get help with these questions 17,18,20,22,23,27,30 &31
Only reply if you are seriously going to help me please
No spam I would really appreciate it
Answer:
17) just take the root of 100. the text says its square(d).
10m
And checking it gives 10m * 10m = 100m²
18) you need to learn some square numbers to ace this topic. it isn't that complicated, just multiply natural numbers with themselves
like
1² = 1
2² = 4
3² = 9
4² = 16
5² = 25
6² = 36
7² = 49
8² = 64
Now we can see that a) sqrt(55) lies between 7 and 8, and that its value is somewhere in between
7 < a < 8
(ignoring the negative solution to the root oc)
try b, c and d yourself. if you struggle, leave a comment.
I got a problem finding exercises 19 to 21, seriously....
22) well...
a * b = 18ft²
6ft * 3ft seems just right. pure guesswork here, seems to be to easy with these numbers.
but we can also write it as a system of two functions
a * b = 18ft²
a = 2b
and then solve it by substituting a in line one with 2b, since a is 2b this is allowed.
2b * b = 18
2 b² = 18
b² = 9
b = 3
(we ignore -3 as a solution bc negative length makes no sense)
plugging that b into line two of the system gives
a = 2 * 3
a = 6
27) rationale can we written as a ratio (a fration)
it almost sounds too simply
rationals are either the root of square numbers, bc they can be solved cleanly, or they got a repeating pattern after the point.
b and c apply to these rules, a and d not
30) lol, I just figured out where the missing exercises are hidden XD
31) just add up the three rectangles (easy part) with the two triangles top and bottom each triangle is just 12m * 16m / 2 (bc it's a triangle, not a rectangle). since you got two triangles you just multiply by two (it's like ignoring the decision. also, the two triangles together would indeed make just a n9ce rectangle).
if you really need the values, leave a comment, but that will not help you in any test.
you can also post your solutions and I'll check them.
32) area of the circle times two
plus area of a rectangle wrapped around the cylinder.
circle are is pi*r² -> pi * (28 in)²
(remember to double for two circles)
rectangle is the circumference of the circle (pi * 28in) times the height of the cylinder
like in 31), feel free two post your results or ask for values if you really struggle to grasp the pattern here.
hope you have a great day and that you understand some more of the topic. you can ace it :)
Find the missing side of the triangle. Round your answers to the nearest tenth if necessary.
12.4 in
3.1 in
16.7 in
11.2 in
Answer:
3.1 in
Step-by-step explanation:
a² + b² =c²
12=c

c²- b² = a²
12²-11.6²= 9.44
√9.44 = 3.07 Rounded = 3.1 in
A triangular prism whose total surface area = 64 cm2, and its lateral area = 40 cm2, find the area of its base?
Answer:
Area of its base = 12cm²
Step-by-step explanation:
The Area of its base = 1/2 of its surface area - 1/2 of its lateral area
Its surface area = 64, then 1/2 X 64 = 32cm²
Its lateral area = 40, then 1/2 X 40 = 20cm²
So, Area of its base = 32 - 20 = 12cm²

What is the radius of each semicircle in this composite figure?
Answer:
2cm
Step-by-step explanation:
First, it is important to define both the radius and diameter. A diameter is the length of a line through the center of a circle that touches two points on the edge.
In the semicircle on the top, if we can imagine it making up a full circle, we can note that the bottom center of the semicircle is the center of the full circle, with the line of length 4cm going right through it. Similarly, for the bottom semicircle, as the line between the semicircles is straight, the diameter for that one is 4cm as well.
The radius is equal to half of the diameter. The diameter is 4cm, so the radius is 4cm/2 = 2cm
