what is the equivalent degree measure of $-\frac{2\pi}{3}$ radians written in simplest terms?
\bigcirc 120°
\bigcirc -120°
\bigcirc -\frac{\pi^2}{270}
\bigcirc -\frac{360°}{3}

Explanation:

Step1: Recall conversion formula

Radians to degrees: multiply by $\frac{180^\circ}{\pi}$

Step2: Apply formula to $-\frac{2\pi}{3}$

$-\frac{2\pi}{3} \times \frac{180^\circ}{\pi} = -120^\circ$

Answer:

B. $-120^\circ$
