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

180(x-2) gives you the SUM of the interior angles.
If you want the measure of each one, divide by x

Just replace x with (x+2y) in both formulas.
