Solution

For degree\'s:
(0- 90 degrees) Quadrant 1 use: the degree given
(91-180 degrees) Quadrant 2 use: 180 - the degree given
(181-270 degrees) Quadrant 3 use: the degree given - 180
271-369 degrees) Quadrant 4 use: 360 - the degree given.

Always make sure your degree is between 0-360 degrees
If its not between 0-360: add 360 (if it is a negative degree) or subtract 360 (if the degree is larger than 360)

Since you have 233 its okay, & it is in Quadrant 3, so...

233 - 180 = 53
So the reference angle is 53 degrees!

same as above

360 - 323 = 37

So the reference angle is 37 degrees!

Add 360° to 157°.

Ac=157°+360°=203

The resulting angle of 203° is positive and coterminal with 157

Ac=203°

Since the angle 203° is in the third quadrant, the reference angle formula is Ar=Ac - 180°

Ar=203° - 180

The reference angle is Ar=53°
