Draw a straight horizontal line. Draw a 29-degree angle below the line. Indicate that 331 is the rest of the space.
Use Protractor Three Times
An angle of 331 degrees is a reflex angle
It is a reflex angle
29 degrees.
29 degrees
A 331 degree angle is a reflex angle and it nearly looks like a circle because there are 360 degrees in a circle.
Add 360, giving the answer as 691 degrees.
360-331=2929 degrees is your reference angle. Remember your signs, though.
180 - 331/3 = 1462/3 degrees.
Since the angle of 331⁰ is in the fourth quadrant, then the measure of its reference angle in the first quadrant is 360⁰ - 331⁰ = 29⁰ .

Oh, dude, the supplement of an angle is just 180 degrees minus the angle itself. So, for 33.1 degrees, you just subtract that from 180 degrees, and you get 146.9 degrees. It's like when you order a pizza and someone takes a slice, the supplement is just what's left in the box!
