Th measure of an interior angle (a) of a regular polygon of n sides is given by:
Set this equal to 170 and solve for n.
Multiply both sides by n.
Simplify the right side.
Subtract 170n from both sides.
Add 360 to both sides.
Finally, divide both sides by 10.

The regular polygon has 36 sides.

That makes the exterior angle 10� (180 - 170).
The sum of exterior angles for ALL polygons is 360
360/10 = 36 sides
