You can put this solution on YOUR website! A polygon has n sides. Three of its interior angles are 50 degrees, 60 degrees and 70 degrees. The remaining(n-3) exterior angles are each 15 degrees. Calculate the value of n.
================
Three of its interior angles are 50 degrees, 60 degrees and 70 degrees --> sum = 180 degrees
---------------
--> a triangle, 3 sides
--> n = 3
