What is the number of sides of a polygon in which the sum of the degree measures of the interior angles is 4 times the sum of the degree measures of the exterior angles?
10.
Sum of the degree measures of exterior angles is 360. S = (n-2)180 = 4 x 360, where n=number of sides.
Solving for (n-2) = 8 or n=10.
