A circular cake is cut into 8 equal pieces. What is the angle measure of each piece? 45°
O
60°
O
15°
O 90°

45°

Step-by-step explanation:

The angles of a circle have to add up to 360°

Since the pieces have to be equal, you have to divide 360 by 8.

360 ÷ 8 = 45

The angle measure of each piece is 45°

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
