I'm assuming that you mean a "regular" polygon!
The measure of an interior angle, A, of a regular polygon of N sides is given by:
Substitute A = 120 degrees.
Multiply both sides by N.
Subtract 120N from both sides.
Add 360 to both sides.
Finally, divide both sides by 60.

The regular polygon has 6 equal sides and is called a hexagon.
