<h3>Answer: $-\frac{\sqrt{3}}{2}$ </h3>

Explanation:

The identity we'll use is cos(-x) = cos(x) for any value of x.

So cos(-150) = cos(150).

Then locate the angle 150 on the unit circle. The terminal point is $\left(-\frac{\sqrt{3}}{2}, \frac{1}{2}\right)$

The x coordinate of this terminal point is the value of cos(150).
