<PRE><B>Question 785293</B>
This is something I answered several weeks ago.  I might try redoing it again now and giving the solution, but instead, I will only say this:


Start with a triangle, add sides one by one, and look for a pattern.
Number of Sides______________Total Angle
3____________________________180
4____________________________360
5____________________________?
6____________________________?
7____________________________?
