Find the Reference Angle 30 degrees

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 reference angles in the first quadrant, which states that the reference angle θ′ is equal to the angle itself: θ′=θ

4. Conclude that the reference angle for 30 is 30

Final Answer

θ′=30
