jennychan12 · Answer

heptagon = 7 sides 
interior angle formula : 180(n-2) n is number of sides
so 6(180) 1080
15x = 1080 
FIND X

A heptagon is a 7-sided polygon.
The sum of the measures of the interior angle of a ploygon is (n - 2)180, where n is the number of sides.
x + x + 2x + 2x + 3x + 3x + 4x = 16x
(7 - 2)180 = 5(180) = 900
16x = 900
Solve for x
