What is the reference angle for an angle with a measure of 331degree?
360-331=2929 degrees is your reference angle. Remember your signs, though.
Why is 90 degree not taken as the angle of reference in trigonometry?
The angle of reference is in the first quadrant, and 90 degrees angle is not in the quadrant.
What is the reference angle for an angle with a measure of 175ô?
5
What is the angle reference for a right angle?
90 degrees
What is the reference angle for an angle with a measure of 175 degree?
5 degrees
What is the reference angle for an angle with the measure of 175 degrees?
The reference angle for an angle with the measure of 175 degrees is 5 degrees
What is the reference angle for an angle with a measure of 331degree?
360-331=2929 degrees is your reference angle. Remember your signs, though.
Why is 90 degree not taken as the angle of reference in trigonometry?
The angle of reference is in the first quadrant, and 90 degrees angle is not in the quadrant.
What is the reference angle of 90 degrees?
Quadrantals are their own reference angle, so 90 degrees.
What is the reference angle for an angle with a measure of 331 degrees?
It is a reflex angle
What is the reference angle to a 140 degree angle?
60
What is the reference angle of 180 degrees?
complementary angle.
What is the reference angle for an angle with a measure of 175ô?
5
What is the angle reference for a right angle?
90 degrees
What is the reference angle sin 285?
Sin(285) is a number, not an angle. The reference angle for 285 degrees is 285-360 = -75 degrees.
What is the reference angle of 331?
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 .
Why is 90 degrees taken as angle of reference in trigonometry?
It is not. The angle of reference is 2*pi radians or 360 degrees.
