A main angle of refrence.
To find the reference angle for negative 200 degrees, first convert it to a positive angle by adding 360 degrees, resulting in 160 degrees. The reference angle is then found by subtracting this angle from 180 degrees, yielding a reference angle of 20 degrees. Thus, the reference angle for negative 200 degrees is 20 degrees.
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.

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.
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

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.
It is not. The angle of reference is 2*pi radians or 360 degrees.
