A regular polygon has 30 sides
....find the angle at each vertex
....find each central angle
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

An exterior angle is  360_degs%2F30 = 12 degs.

An interior angle is  180-12 = 168 degs.

Check for an interior angle:  %28%2830-2%29%2A180%29%2F30 = 168 degs. OK!

A central angle is  360%2F30 = 12 degs.
