The interior angle sum of a convex polygon is 1,520. Hoe many sides does the polygon have

Answer 1

sum of interior angles of a polygon is (n-2)180, where n is number of sides.

here the sum is 1520, so can set up equation to solve for n:

(n-2)180 = 1520

180n - 360 = 1520

180n = 1880

n = 10.4

(your sum is not correct)
