Sin(285) is a number, not an angle.

The reference angle for 285 degrees is 285-360 = -75 degrees.

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 .

Yes; if angle of incidence is zero angle of refraction is zero regardless of index: sin theta r = (n1/n2) sin theta i

type the value of sine in the calculator and press 2ND SIN for sin-1, or press 2ND SIN for sin-1 and type the value of sine, because -sin(.xxxx) = angle known as inverse sine

The reference angle for an angle with the measure of 175 degrees is 5 degrees

-- sin(x) is a number. It's the sine of the angle 'x'. -- sin-1(x) is an angle. It's the angle whose sine is the number 'x'.

Angle greater than 180 degrees are reflex angles.

A main angle of refrence.

sin z = 7/25 = 0.28

360 - 75 = 285

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.
