Find the Reference Angle 30

Problem

30

Solution

1. Identify the quadrant in which the given angle θ=30 lies.

2. Determine that since 0<30<90 the angle is located in the first quadrant.

3. Apply the rule for the reference angle θ′ in the first quadrant, which states that θ′=θ

4. Calculate the reference angle by setting θ′=30

Final Answer

θ′=30
