Only the regular 12-sided ones have.

AL2006 · Answer

The only regular polygon that has an interior angle of 150 degrees is the regular dodecagon, which has 12 sides. We determined this by using the formula for the interior angle of a polygon and solving for the number of sides. This shows that regular dodecagons are unique in having this specific angle measure.
