How to fill out reference angles trigonometry in

01
Start by identifying the angle you want to find the reference angle for.
02
Determine whether the angle is positive or negative.
03
If the angle is positive, subtract 360 degrees from it until you get an angle between 0 and 360 degrees.
04
If the angle is negative, add 360 degrees to it until you get an angle between 0 and 360 degrees.
05
The resulting angle is the reference angle for the original angle.
