Question

What is the measure of each exterior angle of a concave 31-gon?

Answer 1

Around 168.39

Explanation:

The sum of all the angles in a side with n sides is With the n being the total number of sides:

(n-2)180

n = 31

(31 - 2)(180)

= 5220

Now divide that by the number of sides, which is 31:

5220/31

Which round to:

168.39
