5. If the sum of the interior angles of a polygon is 3240 degrees, what type of polygon is it?

assuming it's a convex polygon the equation for the sum of the interior angles in degrees is (n-2)*180 where n is the number of sides.

Well, a line has 0 degrees of interior angle, a triangle has 180 degrees of interior angle, a square has 360 degrees of interior angle, a pentagon has 540 degrees of interior angle.

See a pattern? How can you use this to solve your question?

Oooh, sorry capuchin. My answer gave it away much more than your more helpful advice!

Lol I like asterisk_man answer better but I guess for understanding purposes capuchin answer is appropriate
