51º per interior angle
How many sides does a regular polygon have if the measure of each interior angle is equal to 172 degress ?
Each interior angle measures 170 degrees
Each interior angle measures 165.6 degrees
Now, a 50-gon (the correct term is a pentacontagon, but that takes too long to type) has 50 sides. The equation for the interior angle of a regular polygon (we're talking about a regular 50-gon, right?) is [(n-1)*180]\n where n is the number of sides the polygon has. So in this case, the sum of the interior angles is 8820, and the measure of one angle is 176.4 degrees.
Each interior angle will measure 162 degrees
Providing it's a regular polygon: 360/50 = 7.2 degrees
The measure of each interior angle of a fifteen sided regular polygon, a pendedecagon, is 156o.
It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line

120°
135 Each interior angle of a regular octagon measures 135 degrees.
Each interior angle of a regular 9 sided nonagon measures 140 degrees
Each interior angle of a regular 8 sided octagon measures 135 degrees
A regular trapezoid (!) is a square. And each interior angle of a square is 90 degrees.
A regular polygon having an interior angle measure of 168o has 30 sides and is called a triacontagon.
