Question

The sum of the interior angle of a regular polygon is 1080

find the number of sides of the polygon​

Answer 1

It has 8 sides

Explanation:

This is because the formula is 180(n-2) where n is the amount of sides. An octagon has 8 sides so the sum of the angles is 180(8-2)=180(6)=180×6=1080 degrees

Hope that helps :)

Answer 2

8 sides

Explanation:

(n-2)×180=1080

180n-360=1080

180n=1080+360

180n=1440

n=1440/180

n=8 sides

it's an octagon
