If each interior angle is 20 how many sides does the polygon have?

There is no such polygon but if you meant exterior angles of 20 degrees then it will have 360/20 = 18 sides

Each exterior angle of a regular polygon measures 20 degrees how many sides does the polygon have?

The sum of the exterior angles of any polygon is 360 degrees. If each angle is 20 degrees, there must be 360/20 = 18 such angles. 18 angles means 18 sides so it is an 18-sided polygon.
