Question

I need help with this problem. I don't understand what it means.

Answer 1

ANSWER:

$-\frac{1}{3}\pi$

STEP-BY-STEP EXPLANATION:

Degrees and radians are two different systems for measuring angles. An angle of 360 ° equals 2π radians; an angle of 180 ° equals π radians.

Therefore the formula is the following:

$x\cdot\frac{\pi}{180}=-60\cdot\frac{\pi}{180}=-\frac{1}{3}\pi$
