Find the exact value. cos150°

Aloiza [94]

ANSWER

$\cos(150 \degree) = - \frac{ \sqrt{3} }{2}$

EXPLANATION

We want to find the exact value of cos(150°).

150° makes an angle of 30° with the positive direction of the x-axis and it is also in the second quadrant.

The cosine ratio is negative in the second quadrant.

Using the unit circle,

$\cos(150 \degree) = - \cos(30 \degree) = - \frac{ \sqrt{3} }{2}$
