Any polygon can have an interior angle of any measure (between 0 and 360 degrees).
A regular polygon having an interior angle measure of 168o has 30 sides and is called a triacontagon.

The sum of the exterior angles of a polygon is 360o. For a regular polygon, these are all equal. For an interior angle of 168o the exterior angle is 180o - 168o = 12o Therefore number of sides = 360o / 12o = 30.
It is a triacontagon, or 30-sided shape.The formula for one interior angle of a regular n-sided polygon is 180(n-2)/nwhere 180 (28) / 30 = 168*You can QUICKLY and EASILY find the answer using the formula for one exterior angle : it is 360/n360/30 = 12 and the interior angle is 180-12 = 168.The algebraic equation is(180-168) n = 360
let n be the number of sides on the regular polygon (180*(n-2)) / n = Interior angle = 720 / 6 = 120 External Angle = 360 - [Interior Angle] 360 - 120 = 240 however in some cases the exterior angle will be 180 - [interior angle] 180 - 120 = 60 , if this is for homework it depends on how your teacher has taught you
