What is the exterior angle of a 30 sided polygon? – WisdomAnswer
WebSep 26, 2012 · 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. WebAug 6, 2024 · Each exterior angle of a regular polygon = 30 deg. The number of sides in the polygon = 360/30 = 12. The number of diagonals = n (n-3)/2 = 12* (12–3)/2 = 6*9 = 54. Number of sides = 360/External Angle rearrangement if usual EA formula fir regular polygons) gives us 12 sides. Web2 Answers. The Dragon answered.
