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
