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.

Because a right angle is a right angle.
The reference angle for an angle with the measure of 175 degrees is 5 degrees
Given the reference perspective of a specific angle the sides are are the adjacent sides and the opposite side If we have a right triangle the longest side (opposite the right angle) is the hypotenuse.
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.
Quadrantals are their own reference angle, so 90 degrees.
If there is no length for the hypotenuse you have to use the Pythagorean Theorem. If there are two sides missing and a reference angle you could use Trigonometry.
It is a reflex angle

complementary angle.

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