If the name on the degree of the angle d , then the exterior angle is 180 - d. The exterior angles must add to 360, a full circle to return to where it started. So if there are n sides and n angles, n(180-d) = 360 solving for d, we obtain 180 n - nd = 360 -nd = 360 - 180n -d = 360/n - 180, and then d = 180 - 360/n
