Try making a general formula for the sides of a regular polygon from pictures. A useful hint would be, remember that you can make any regular polygon into a bunch of equal triangles and the center contains a full 360 degrees and all triangles have 180 degrees.

anonymous · Answer

it can be the number of factors 360 will have 
and its 22 (leaving 0 and 360)

yep..22 seems correct to me as well..

anonymous · Answer

so is C the answer

anonymous · Answer

see each int angle of regular poly gon is given by 180 -(360/n)

anonymous · Answer

ya i gt the formula thanks all:)
