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
-- 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'.
The reference angle for an angle with the measure of 175 degrees is 5 degrees
Angle greater than 180 degrees are reflex angles.
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.
sin(37) = 0.6018150232
sin z = 7/25 = 0.28
A main angle of refrence.
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.
