Question

If the sum of all interior angles of a regular polygon is 1080 degrees then number of sides of the polygon is?

Answer 1

Answer:  8

Step-by-step explanation:

The formula for the sum of the angles of a polynomial is:

$S_n=180(n-2)$

1080 = 180(n - 2)

1080 = 180n - 360

1440 = 180n

8 = n
