WebHow many sides does a polygon with an exterior angle of 30 have? Since all the angles are congruent, 30a=360, and a=12. Since a=s, s=12, so the polygon has 12 sides. What is the … WebDec 17, 2011 · The total interior angle of a 12 sided polygon is = (12 - 2) 180 degrees = 1800 degrees. The internal angle at each vertex of an regular dodecagon is equal to = = 150 degrees. While the exterior angle at a single vertex is = = 30 degrees. The total exterior angle of a 12 sided polygon is 360 degrees.
