Answer 1

@ranga

Answer 2

\(\bf \textit{exterior angle}\times \textit{sides}=360^o\implies \textit{sides}=\cfrac{360^o}{\textit{exterior angle}}\)

Answer 3

The sum of all the exterior angles of a polygon adds to 360 degrees.

Assume there are n sides to the polygon. Diagram shows each exterior angle = 15
For n sides it will be 15 x n

Equate 15n to 360 and solve for n.
