Question 762265: Find the number of sides of a polygon if the sum of the measures of its interior angles is twice the sum of the measures of its exterior angle Answer by solver91311(24713) (Show Source):
The sum of the measures of the exterior angles of any polygon is 360 degrees. The sum of the measures of the interior angles of a polygon with sides is given by . Set the expression for the sum of the measures of the interior angles equal to twice the sum of the measures of the exterior angles and then solve for
