convert 120 degrees to radians.

Explanation:

Set up conversion factor

$$ 1^{\circ} = \frac{\pi}{180} \text{ radians} $$

Multiply by given angle

$$ 120^{\circ} = 120 \times \frac{\pi}{180} \text{ radians} $$

Simplify the fraction

$$ 120 \times \frac{\pi}{180} = \frac{120}{180}\pi = \frac{2}{3}\pi \text{ radians} $$
