Find the reference angle $\theta =\frac{2\pi }{3}$?

Paola Hays

The question is seemingly about $\theta =\frac{2\pi }{3}$
This angle, when calculated counterclockwise, is definitely in the second quadrant. This angle's terminal side forms an acute angle with the x axis of $\frac{\pi }{3}$. The reference angle is therefore $\frac{\pi }{3}$
