Find the Reference Angle tan(150) Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Use of calculator to Find the Quadrant of an Angle 1 - Enter the angle: in Degrees top input. Make the expression negative because tangent is negative in the second quadrant. Keep doing it until you get an angle smaller than a full angle. A circle has a total of 360 degrees all the way around the center, so if that central angle determining a sector has an angle measure of 60 degrees, then the sector takes up 60/360 or 1/6, of the degrees all the way around. In that case, the sector has 1/6 the area of the whole circle. All cuts on a straight board leave 2 angles as measured with a protractor.
