Choose the point on the terminal side of -210°.

Answer 1

@TuringTest

Answer 2

How long is the line segment?

Answer 3

(-1, 1)
(-1,sqrt3)
(sqrt3, -1)
(-sqrt3, 1) are the options @CliffSedge

Answer 4

OK, then you can use this to test them:
\[\tan(\theta) =y/x\]
Find the tangent of 210º and that . . . . hold up, I didn't see that negative sign there...
(I'll have to redraw my picture)
Find tan(210º) and that has to equal the ratio of the y-coordinate to the x-coordinate.

Answer 5

You can also tell from which quadrant it's in what the signs on x and y have to be.

Answer 6

-sqrt3 and 1 right

Answer 7

Correct.
