Find the Reference Angle 235

Problem

235^∘

Solution

1. Identify the quadrant in which the given angle θ=235^∘ lies. Since 180^∘<235^∘<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. Subtract the values to find the reference angle.

235^∘−180^∘=55^∘

Final Answer

θ^′=55^∘
