So cos(-150) = cos(150).
Then locate the angle 150 on the unit circle. The terminal point is 
The x coordinate of this terminal point is the value of cos(150).
C is right. She has partially completed the construction. Her next step is to use the arc markings to determine the radius to construct the circle.
