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

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.
