OpenStudy (blacksteel):

Assuming that the shape is supposed to be a regular polygon, the answer is 54. The sum of a polygon's angles is 180*(sides - 2), so the sum of the angles of a pentagon is 540. Then if the pentagon is regular, each angle has a measure of 108, so half of that angle would be 54.

Looking at the question, though, we probably can't assume the polygon is regular - do you know anything about the values of 1 or 2?
