The reference angle for 325 degrees is 35 degrees which is found by subtracting 325 from 360 since it is in the third quadrant.
complementary angle.
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 .
Sin(285) is a number, not an angle. The reference angle for 285 degrees is 285-360 = -75 degrees.

353 degrees is a reflex angle
A reflex angle
The reference angle for an angle with the measure of 175 degrees is 5 degrees
A main angle of refrence.
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.
Quadrantals are their own reference angle, so 90 degrees.
It is a reflex angle
