Final answer:

The value of sin(-210°) is -0.5.

Step-by-step explanation:

To find the value of sin(-210°), we can use the unit circle. In the unit circle, the sine function gives us the y-coordinate of a point on the circle corresponding to an angle. Since -210° is in the third quadrant, the angle will have a negative y-coordinate. Using the unit circle, we can find that sin(-210°) = -0.5.
