The size of each interior angle of a regular polygon is 156 degrees. Workout the number of sides of the polygon.

Im so confused? Dont all interior angles equal 180? How can the angle be so big?

You must know a couple of formulae about interior and exterior angles of a polygon?

If you're confused, the best thing to do is the basic background reading, then try and solve the problem. Post your working if you're stuck.
