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

Step-by-step explanation:

Recall that the value of the cosine of an angle in the unit circle is the horizontal value (x-coordinate) read-out for the point on the circle's circumference that represents the given angle.

in this case, notice that 150^o corresponds to an angle in the second quadrant, and the actual coordinate values for it are given to you. therefore, use the value you read for the x-coordinate: $-\frac{\sqrt{3} }{2}$
