Answer 1

What is the sum of the angle measures of a 32-gon?

A. 5400
B. 5760
C. 6120
D. 5580

Answer 2

I think it's A.

Answer 3

The sum of the measures of the interior angles of a convex polygon with n sides is

%28n-2%29%2A180%5Eo , or %28n-2%29%2Apiradians .
If n=32 , then that sum is
30%2A180%5E2=5400%5Eo or 30piradians

Answer 4

I can never remember the direct formula
i use the fact that sum of external angles of any polygon = 360
so here external angle of regular 32-gon = 360 / 32 = 11.25
internal angle = 180 - 11.25 = 168.75

32 *168.25 = 5400 degrees

Answer 5

A is correct
