Case 2: (For Angles between 90° to °) – When the terminal side is on the second quadrant, the reference angle is ° minus our given angle. So, if the given angle is °, then its reference angle is (° – ° = 75°). Hence, Reference Angle = ° – Given [HOST]g: zoro Angle, θ. Reference Angle Formula in Degrees.
