Question

If the measure of each exterior angle of a regular polygon is 9°, determine how many sides the polygon has.

Answer 1

polygon are 2 dimensional shape

Answer 2

The sum of all the exterior angles for any regular polygon equals 360°;
Therefore if each exterior angle is equal to 9°, the number of exterior angles, which is equal to the number of sides, is found by:
360/9 = 40
Therefore the polygon has 40 sides.
