Find the Reference Angle 110

Problem

110

Solution

1. Identify the quadrant in which the given angle θ=110 lies. Since 90<110<180 the angle is in Quadrant II.

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

3. Substitute the value of the angle into the formula: θ′=180−110

4. Subtract the values to find the reference angle.

Final Answer

θ′=70
