Question 510290: The measure of an exterior angle of a regular polygon is given. Find the measure of an interior angle, and find the number of sides. The measure of the exterior angle is 72 degrees.
I found that the adjacent angle is 108 degrees. That is as far as I got. Can you explain this? Thank you.
