Find the Reference Angle 70

Problem

70

Solution

1. Identify the quadrant in which the given angle θ=70 lies.

2. Determine that since 0<70<90 the angle is located in the first quadrant (Quadrant I).

3. Apply the rule for reference angles in Quadrant I, which states that the reference angle θ′ is equal to the angle itself: θ′=θ

4. Conclude that the reference angle is 70

Final Answer

θ′=70
