If the sum of the interior angles of a regular polygon is 1080 degrees how many sides does this polygon have?

Formula to find sum of interior angles (when n = number of sides): 180(n-2) Sub in total and solve for n: 180(n-2) = 1080 180n-360 = 1080 180n = 1080 + 360 180n = 1440 180n/180 = 1440/180 n = 8 Thus, the number of sides is 8 and it is a hexagon.
