What is the angle reference for a right angle?
90 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 -410degree?
It is 310 degrees.
What is the reference angle for an angle with a measure of 175 degree?
5 degrees
An angle that measures 210 degrees is?
An angle that measures 210 degrees is a reflex angle.
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 one is a reflex angle 90 degrees or 210 degress?
210 degrees.
What is the reference angle of 90 degrees?
Quadrantals are their own reference angle, so 90 degrees.
Find the reference angle for the angle 59 degrees?
90 degrees
What is the reference angle of 353 degrees?
353 degrees is a reflex angle
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.
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 180 degrees?
complementary angle.
What is the angle reference for a right angle?
90 degrees
What type of angle is 210 degrees?
An angle that is 210 degrees would be considered a "Reflex" angle. This is because its measurements exceed 180 degrees. Anything above 90 degrees is "obtuse". Once you hit 180 it becomes a "straight" line and anything above that is a "reflex".
What is the reference angle of 320 degrees?
40 degrees
