Question

If the sum of the interior angles of a polygon is 540, then how many sides does the polygon have?

A. 5
B. 6
C. 7
D. 8

Answer 1

(A.) 5

Explanation:

(n-2) (180) =540

(n-2)180/180 = 540/180

n-2 =3

n = 3+2=5

n=5

Answer 2

Number of Sides = (Sum of Interior Angles ÷ 180) + 2
Number of Sides = (540/180) + 2
Number of Sides = 3 + 2
Number of Sides = 5
answer is A
