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 .
A 331 degree angle is a reflex angle and it nearly looks like a circle because there are 360 degrees in a circle.
Since a full circle is 360°, a 331° angle is the outside measure of a 29° angle.

complementary angle.
Sin(285) is a number, not an angle. The reference angle for 285 degrees is 285-360 = -75 degrees.
It is a reflex angle
29 degrees.
29 degrees
360-331=2929 degrees is your reference angle. Remember your signs, though.
An angle of 331 degrees is a reflex angle
A 331 degree angle is a reflex angle and it nearly looks like a circle because there are 360 degrees in a circle.
Draw a straight horizontal line. Draw a 29-degree angle below the line. Indicate that 331 is the rest of the space.
To draw an angle of 331 degrees using a protractor, first, draw a straight line that will serve as the initial side of the angle. Place the center hole of the protractor at the endpoint of the line and align the baseline of the protractor with the line. Since 331 degrees is greater than 180 degrees, measure 331 degrees by counting clockwise from the 180-degree mark on the protractor. Mark the point at 331 degrees and then draw a line from the center point through this mark to complete the angle.
Since a full circle is 360°, a 331° angle is the outside measure of a 29° angle.
The reference angle is the acute angle formed by the terminal side of an angle and the x-axis. For an angle of 243 degrees, which is in the third quadrant, the reference angle can be found by subtracting 180 degrees from it. Thus, the reference angle is 243° - 180° = 63°.
The reference angle for an angle with the measure of 175 degrees is 5 degrees
