Answer:
All of the angles are 60°, because 180÷3 is 60. so the measure of angle b plus the measure of angle a and angle c is equal to 180°. The measure of angle a + 120° is 180
If the diameter is 8 centimeters, the radius is 4. We can use the formula

and plug in r=4 and h=13 to get

, so

.
Answer:
$482.625 ≈ $482.63
Step-by-step explanation:

y · 100 = 450 · 7.25
100y = 3262.5
100y ÷ 100 = 3262.5 ÷ 100
y = 32.625
$450 + $32.625
$482.625
Are you trying to solve for c? if so c=8
