Question

Find the number of sides of a regular polygon having sum of interior and exterior 1260.

Answer 1

Answer:

We know that sum of interior angles of a regular polygon is (n - 2) ×180.

(1) Given sum of interior angles = 1260.

(n-2)×180 = 1260

(n-2) = 1260/180

(n-2) = 7

n = 7+2

n = 9.

Therefore the number of sides = 9.
