You can put this solution on YOUR website!
The sum of the measures of the exterior angles of any
polygon is 360°.  Since the 20-sided polygon is a regular 
polygon, all 20 exterior angles have the same measure,
so each is %22360%B0%22%2F20 or 18° each.  The green lines
below form one exterior angle of the 20-sided polygon.
It's interesting that each exterior angle is congruent to
every central angle.  As you see below, each central angle 
also has measure 18°.
