Oh, dude, that's an easy one! A polygon with a 30-degree interior angle is a 12-sided polygon, also known as a dodecagon. So, like, if you ever need to impress someone with your polygon knowledge at a party, just drop that fun fact and watch the crowd go wild.

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
