A nonogon has 9 sides
The sum of the interior angles of a polygon of n sides is 180o * (n-2). For a regular nonagon (9 sides), the sum is (9 - 2) * 180o = 1260o, so each interior angle is 1260o / 9 = 140o. The exterior angle is the supplement of the interior angle: 180o - 140o = 40o.

There are 27 diagonals in a nonagon.
