The interior angles of a 30-gon add up to 5040 degrees
5040
Each interior angle can have any value in the range (0, 360) degrees - excluding 180 degrees. The only restriction is that the interior angles sum to 5040 degrees.
The sum of the exterior angles of any polygon is 360 degrees. So for a regular dodecagon (12-gon), each exterior angle is 360/12 = 30 degrees. And so, each interior angle is 180 - 30 = 150 degrees.
