Three interior angles of of a polygon are 150 each. If the remaining exterior is 45. Find the number of sides of the polygon
-------------
--> Three exterior angles of of a polygon are 30 each. If the remaining exterior is 45. Find the number of sides of the polygon
----
3*30 + x*45 = 360
45x = 270
x = 6
--> 9 sides
