19. What is the sum of the measures of the exterior angles in a nonagon? Explain.

A nonagon has 9 sides. The angles of the nonagon (or any regular polygon) all equal 360 degrees. To find the measure of one exterior angles you would divide 360 by the number of angles. 360/9=40. One exterior angle is 40 degrees.
