Question

Find radian measure of degrees.. also how would I find this answer on a calculator

Answer 1

FORMULA

`\pi rad=180^0`

Convert 120 degree to radian by multiplying by pi and dividing by 180

`\begin{gathered} \Rightarrow(120\pi)/(180) \\ (2\pi)/(3) \end{gathered}`

Given a negative angle, we add 360 to get its corresponding positive angle.

The answer can also be 2.09 rad
