What are we exactly supposed to solve for here
No it is not because 15 out of 30 is half but 12 out of 20 is more than half

The exterior angles of a polygon all add to 360, if you need to find an exterior angle when given the number of sides and that all angles are equal you simply do: 360/ number of sides.
When you need to find the exterior angle when given an interior angle, you do: 180- interior angle.
Hope this helps :)
