Question

The sum of the interior angles in a polygon is 15,480°. Calculate the number of sides in the regular polygon.

Answer 1

88 sides

Explanation:

The sum of the interior angles of a polygon is

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

180° (n - 2) = 15480° ( divide both sides by 180° )

n - 2 = 86 ( add 2 to both sides )

n = 88
