If each interior angle of a regular polygon measures 120°, how many sides does the polygon have?
+%28%28n-2%29%2A180%29%2Fn+=+120+
n = number of sides
+%28n-2%29%2A180+=+120%2An+
+n+-+2+=+%28120%2F180%29+%2A+n+
+-2+=+%282%2F3%29n+-+n+
+-2+=+%28-1%2F3%29n+
+2+=+%281%2F3%29n+
+6+=+n+
6 sides, it is a hexagon
