Question

find the number of sides of a polygon whose exterior angle is 45°​

Answer 1

We do this by dividing 360° by the number of sides, which is 8. (b) Calculate the size of each interior angle in the regular octagon. We do this by subtracting the size of each exterior angle, which is 45°, from 180°. A regular polygon has equal exterior angles of 72°.

Answer 2

Divide 360 by the difference of the angle and 180 degrees. For the example, 360 divided by 15 equals 24, which is the number of sides of the polygon. Divide 360 by the amount of theexterior angle to also find the number of sidesof the polygon.
