Let n equal the number of sides in a regular polygon. For 3 <= n < 25, how many values of n result in a regular polygon where the common degree measure of the interior angles is not an integer?
We just need to find the non-integer solutions for this
(n - 2) 180 / n
n = 7, 11, 13, 14, 16,17, 19, 21, 22, 23
