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 .
353 degrees is a reflex angle
nwater * sin 30=nair *sin(angle of refraction) 1.33*0.5=1*sin(angle of refraction) sin(angle of refractiob)=0.665 angle of refraction inair=41.6 degrees nwater * sin 30=nair *sin(angle of refraction) 1.33*0.5=1*sin(angle of refraction) sin(angle of refractiob)=0.665 angle of refraction inair=41.6 degrees
The reference angle for an angle with the measure of 175 degrees is 5 degrees
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
A main angle of refrence.
-- 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'.
sin(37) = 0.6018150232
Angle greater than 180 degrees are reflex angles.
The angle of reference is in the first quadrant, and 90 degrees angle is not in the quadrant.
360-331=2929 degrees is your reference angle. Remember your signs, though.
Quadrantals are their own reference angle, so 90 degrees.
The term angle of deviation is used in reference to a prism.
It is a reflex angle
