Find the interior and exterior angle measurements of a polygon with this many sides:

x=2y

help? I don't want the answer, I just would like to know how to do this one.

I don't see why a number of sides is being specified as an equation.
The SUM of the exterior angles of a polygon is always 360 degrees. If there are x sides, AND IF the angles at each vertex are equal (as in the case of a regular polygon), each exterior angle is 360/x degrees.

Each interior angle of a regular polygon with x sides is 180 (x-2)/x

Oh. I'm sorry. I meant 2x+y

    If I have a polygon with x+2y sides, how do I find the interior and eterior angle? I know that to find the interior angle you use 180(x-2) and for the exterior you use 360/x. But do i just plug in x+2y for every x? I'm lost
