Question

Choose the point on the terminal side of -210°

A) -1, 1
B) -1, √3
C) √3, -1
D) -√3, 1

Answer 1

To choose the point on the terminal side of -210°, we need to find the coordinates of the point on the unit circle associated with this angle.

Step-by-step explanation:

To choose the point on the terminal side of -210°, we need to find the coordinates of the point on the unit circle associated with this angle.

For an angle of -210°, the terminal side lies in the third quadrant. Therefore, the x-coordinate will be negative and the y-coordinate will also be negative.

Among the given options, the point with both negative x and y coordinates is (C) √3, -1.
