Recall the Polygon Interior Angles Sum Theorem.

3240

Practice makes perfect

Recall the Polygon Interior Angles Sum Theorem.

Polygon Interior Angles Sum Theorem
The sum of the measures of the interior angles of an n-gon is (n-2)180.

We are given convex 20-gon, so we have to substitute n=20. ( 20-2)180=3240
