Question

Find the sum of the interior angles of a 22-sided polygon.

Group of answer choices
1,980°
2,160°
3,360°
3,600°

Answer 1

3360°

Explanation:

180n-360= sum of interior angles

Answer 2

3600°

Explanation:

the sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 22 , then

sum = 180° (22 - 2) = 180° × 20 = 3600°
