To find answers like this you use the formula (S-2)*180 s= sides so you would get 1800 then you divide it by the number of sides(12) to get 150 but since its about exterior angles you subtract it from 180 which is 30 degrees.

the formula for the degree of the interior angle of a regular polygon is (n-2)180/n where n is the number of sides. so just plug it in and you get 10(180)/12. so each INTERIOR angle is 150 degrees. to find the exterior angle subract the interior from 360 so each exterior angle of a 12-gon is 210 degrees. next time PLEASE post in the right section!

Formula: 180(n-2)/n
180(12-2)/12
=150 degrees
