The interior angles of a polygon with n sides is
180(n-2). If n= 12, the interior angles total 1800. For 12 angles, the sum of the interior and exterior angles is 180x12= 2160. Thus the exterior angles total 360. If you are talking a regular dodecagon, the measures are 150 and 30 respectively,.

You can't actually find the seperate interior angles of a dodecagon, because the lengths of each side could be different. If it were a regular dodecagon, it wou;d have been different. The sum of all the interior angles would be 1800. Each seperate angle is 150.
