You can put this solution on YOUR website! A polygon has 3 interior angles which measure 150 degrees. The remaining exterior angles each measure 45 degrees. How many sides does the polygon have?
--------------------
Use exterior angles:
A polygon has 3 exterior angles which measure 30 degrees. The remaining exterior angles each measure 45 degrees. How many sides does the polygon have?
------------
3*30 + x*45 = 360
x = 6
--> 9 sides
