A polygon has 2 interior angles of 120 degrees each. and the others are each 150 degree calculate
A) number of sides
B) sum of angles
------------
The sum of the interior angles (# of sides = n) has to be an integral multiple of 180 degs, and the sum of the Int angles is 180*(n-2)
----
2*120 + 150(n-2) = 180*(n-2)
Solve for n.
