Question

How can you convert -150° to radians?

Answer 1

7pi/6

Step-by-step explanation:

we use the unit circle and since it is negative we have to use the terminal angle by adding 360 to - 150 and get 210 and we look at the unit circle we get 7pi/6

Answer 2

You can convert -150 degrees to radians by multiplying it by π/180

`-150\text{ degre}e\text{ }=-(5)/(6)\pi\text{ radian}`

Step-by-step explanation:

We want to convert -150 degrees to radians

Note that

1 degree = π/180 radians

Let

-150 degree = x radians

Then

`\begin{gathered} x=(\pi)/(180)*(-150) \\ \\ =-(5)/(6)\pi \end{gathered}`
