find the sum of the interior angles of 12 sides​

Sagot :

Answer:

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. ... The total exterior angle of a 12 sided polygon is 360 degrees.
