Question

If the sum of the interior angle measures of a polygon is 3600°, how many sides does the polygon have?


A. 22 sides
B. 20 sides
C. 18 sides
D. 10 sides

Answer 1

well the formula fot the sum of the interior angles is

\[Angle ~~Sum = (n - 2) \times 180\]

where n is the number of sides

substituting your information you get

\[3600 = (n - 2) \times 180\]

now just solve for n
