If it is a regular nonagon, then you use the following formula:
[(s-2) x 180]/s = angle of one interior angle. (s means the number of sides)
Then solve: [(s-2) x 180]/s = [(9-2) x 180]/9 = [7 x 180]/9 = 1260/9 = 140.
Then, for the exterior angle, subtract 140 from 360. The measure of the exterior angle of a regular nonagon is 220.
