Question

if the sum of the interior angles of a regular polygon is 900 degrees, how many sides does the polygon have?

Answer 1

Sum of Interior Angles = (Number of Sides -2) • 180 degrees

Number of Sides = (Sum of Interior Angles / 180) +2

Number of Sides = (900 / 180) +2

Number of Sides = 7

It's a heptagon

Answer 2

7. It is a heptagon

Explanation:

900 = (n - 2)180

900 = 180n - 360

900 + 360 = 180n - 360 + 360

1260 = 180n

n = 7
