Which value is closest to the perimeter of the window
Eddi Din [679]

Answer:

9.82 feet

Step-by-step explanation:

the perimeter of the window is the circumference of a semi-circle with a diameter of 5

P = (πd)/2     (divided in half because it's only half a circle)

P ≈ 3.14(3.5) which is approx 11

11 is closest to 9.82

An angle measures 32° more than the measure of its supplementary angle. What is the measure of each angle?
ValentinkaMS [17]

Answer:

29°; 61°

Step-by-step explanation:

Let one angle  = x°

Other angle = (x + 32)°

x + x + 32 = 90   {given they are complementary}

2x + 32 = 90

2x = 90 -32

2x = 58

x = 58/2

x = 29

One angle  = 29°

Other angle = 29 + 32 = 61°

I need help with my geometry homework! Thank you! I will mark brainliest!!!!
Firlakuza [10]

Answer:

The first choice is the one you want

Step-by-step explanation:

Use geometric means to solve for a first. The formula is

8^2=15a and 64 = 15a and a = 64/15

That one was quite easy.  Finding b is a bit more difficult.

The formula for finding b is

\frac{a}{b}=\frac{b}{15+a}

Solving for b:

b^2=a(15+a)

Filling in we have

b^2=15(\frac{64}{15})+(\frac{64}{15})^2 and

b^2=64+\frac{4096}{225} and

b^2=\frac{18496}{225} so b = 136/15
