Find the Reference Angle 240 degrees

Problem

240

Solution

1. Identify the quadrant in which the given angle θ=240 lies. Since 180<240<270 the angle is in Quadrant III.

2. Apply the formula for the reference angle θ′ in Quadrant III, which is θ′=θ−180

3. Substitute the value of the angle into the formula to calculate the result.

4. Subtract the values to find the reference angle.

240−180=60

Final Answer

θ′=60
