Question

1. the reference angle of 188° is

a. 8°
b. 12°
c. 98°
d. 188°

Explanation:

Step1: Determine quadrant of \(188^\circ\)

\(180^\circ < 188^\circ < 270^\circ\), so it's in the third quadrant.

Step2: Calculate reference angle

For an angle \(\theta\) in the third quadrant (\(180^\circ < \theta < 270^\circ\)), the reference angle is \(\theta - 180^\circ\).
So, reference angle of \(188^\circ\) is \(188^\circ - 180^\circ = 8^\circ\).

Answer:

A. \(8^\circ\)
