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.
5
90 degrees
the angle the theoretical incident ray makes with the final refracted ray
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.
A main angle of refrence.
Quadrantals are their own reference angle, so 90 degrees.
It is a reflex angle
60
complementary angle.
