Frank cut a pie into 10 equal slices there were only 3 slices left what is the measure of the angle

Given that a circle is 360 degrees and he made ten equal slices, what you would do is...

360/10 = 36 degrees per slice.

Given that there were seven slices taken, you take 36 and multiply it by 7 to get 252 degrees.

The angle that was taken is 252 degrees, while the angle of the pieces that are left over is 108 degrees.

I hope that helped!

Hey there, 10 equal slices is 360, so 360/10=36, 3*36=108, Therefore, the measure of the angle is 108°
