Question

A polygon has 11 sides. What is the sum of the measure of the interior angles of the polygon?. . A] 1800°. B] 1620°. C] 1440°. D]1980°

Answer 1

The formula for the sum of the interior angles of a polygon with n sides is
 (n - 2)180°
Substituting n = 11
Sum of angles = (11 - 2)180°
S= 9 x 180°
S= 1620°
So the best answer is option B
