One interior angle of a convex polygon is 160 degrees. The rest of the interior angles of the polygon are each 112 degrees. How many sides does the polygon have?
Sum of interior angles of a polygon (n-2)180
THIS polygon sum = 160 + (n-1)112 set these two equations =
(n-2)180 = 160 + (n-1)112 and solve for n = 6
