Answer:Each interior angle of the polygon is 108 degrees, so each exterior angle of the polygon is 180-108 = 72 degrees. So the number of sides is 360/72 = 5

It’s 5 side and 180 degrees for a pentagon, 4 sides and 90 degrees for a quadrilateral, 3 sides and 60 degrees for a triangle.

I hope this helps. Good luck!!!
