Exercise 12 Page 532

The Polygon Interior Angles Sum Theorem says that the sum of the measures of the interior angles of an n -sided convex polygon is (n-2)180.

2340

Practice makes perfect

The Polygon Interior Angles Sum Theorem states that the sum of interior angle measures of a n-sided convex polygon is ( n-2)180. To find the sum of the measures of the interior angles of a 15-gon, we have to substitute 15 for n in this expression.

( 15-2)180=2340
