An exterior angle of a regular 17-gon is 360/17~~21.1765^o or 21 3/17degrees. An exterior angle of a 28-gon is 360/28~~12.857^o or 12 6/7degrees.

Explanation:

All convex polygon's exterior angles add up to 360 degrees.To solve for a regular n-gon's exterior angle, you take 360/n where n is the number of sides the polygon has.
