360-331=2929 degrees is your reference angle. Remember your signs, though.
The angle of reference is in the first quadrant, and 90 degrees angle is not in the quadrant.
A main angle of refrence.

The reference angle for an angle with the measure of 175 degrees is 5 degrees
360-331=2929 degrees is your reference angle. Remember your signs, though.

A main angle of refrence.
Quadrantals are their own reference angle, so 90 degrees.
It is a reflex angle

Sin(285) is a number, not an angle. The reference angle for 285 degrees is 285-360 = -75 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 .
