the answer is C
why:
because you use this function
180(n-2) to find total degrees in any polygon
then you divide that number by the number of angles
in this case 5.
hope it helped :)

The interior angle measure of a regular n-sided polygon is given by %28%28n-2%29%2A180%29%2Fn. A pentagon has 5 sides, so:

%28%285-2%29%2A180%29%2F5=%283%2A180%29%2F5=540%2F5=108. Answer C. Final answer.
