Question

The sum of the interior angles of
an n-sided polygon is 3600. The
value of n is [? ].

Answer 1

Answer: 22

=====================================================

Work Shown:

S = sum of the interior angles of a polygon with n sides

S = 180(n-2)

3600 = 180(n-2)

3600/180 = n-2

20 = n-2

20+2 = n

22 = n

n = 22
