Question

Out how many sides are there in a regular polygon whose interior angles have the sum of 1080.

Answer 1

8 sides

Explanation:

the sum of the interior angles of a polygon is calculated as

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

here sum = 1080° , then

180° (n - 2) = 1080° ( divide both sides by 180° )

n - 2 = 6 ( add 2 to both sides )

n = 8

the number of sides in the regular polygon is 8
