90 degrees
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.
It is 310 degrees.
5 degrees
The reference angle for an angle with the measure of 175 degrees is 5 degrees
No
Quadrantals are their own reference angle, so 90 degrees.
90 degrees
353 degrees is a reflex angle
It is not. The angle of reference is 2*pi radians or 360 degrees.
Sin(285) is a number, not an angle. The reference angle for 285 degrees is 285-360 = -75 degrees.
The bond angle in NI3 is approximately 107 degrees.
The bond angle for NBr3 is approximately 107 degrees.
complementary angle.
90 degrees
The supplement of an angle is the angle that, when added to the original angle, equals 180 degrees. Therefore, the supplement of an angle measuring 73 degrees would be 180 degrees minus 73 degrees, which equals 107 degrees.
