text: how many sides does an equiangular polygon have if each angle measuares 170 degrees? plz explain and show how to do it, don't just tell me the answer, i really need to know so i can do the rest of my 15 problems!!! guess, what, there is an equation for this  think about it the equation of the angle of a polygon is   n= side ((n-2)*180)/n = teh measure of each angle  so for this  ((n-2)*180)/n = 170 so  (n-2)*180 = 170n 180n-360 = 170n -360=-10n n=36  there are 36 sides in this polygon  hope this helps, any questions e-mail me matttlocke@yahoo.com
