Question

the interior angle of a regular polygon is 180⁰. Find the number of sides of a polygon.​

Answer 1

Each interior angle of a regular polygon is 135 degree then find the number of sides. Therefore the number of sides of the regular polygon is 8.

Answer 2

Hello, this is the wrong question. 180 cant be the question. I think it has been mistaken for 108. For 108, here is the answer:

⇒ 180(n−2)/n = 108°

⇒ 180n − 360 = 108n

⇒ 72n = 360

⇒ n = 5
