hi lex,

Welcome to the forum.

You haven't given us any background to explain what these questions are about. The title is polygons, so I thought this might be the numbers of sides (N) and either the total angle sum, the exterior angle or interior angle if the polygon is regular. But I cannot make any of the answer choices fit with any of those possibilities, so I'm stuck with how to help. Please give the whole question and a diagram if possible. If you cannot show a diagram then describe in words.

Thanks,

Bob
