Question

Which ordered pair is on the unit circle at 150 degrees? \left(-\frac{\sqrt{2}}{2},\:-\frac{\sqrt{2}}{2}\right)( − 2 2 , − 2 2 ) \left(-\frac{\sqrt{2}}{2},\:\frac{\sqrt{2}}{2}\right)( − 2 2 , 2 2 ) \left(-\frac{\sqrt{3}}{2},\:-\frac{1}{2}\right)( − 3 2 , − 1 2 ) \left(-\frac{\sqrt{3}}{2},\frac{1}{2}\right)

Answer 1

(
`(-√(3) )/(2) , (1)/(2)`)

Explanation:

Let's use unit circle to see the value of 150 degrees in the ordered pair form of (cos 150°, sin 150°).

We get (
`(-√(3) )/(2) , (1)/(2)`)
