Find the Reference Angle 210

Problem

210^∘

Solution

1. Identify the quadrant in which the given angle θ=210^∘ lies. Since 180^∘<210^∘<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: θ^′=210^∘−180^∘

4. Subtract the values to find the reference angle.

Final Answer

θ^′=30^∘
