Question

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

(-1, 1)

(-1, square root of three)

(square root of three, -1)

(negative square root of three, 1)

Answer 1

what quadrant do we end up in?

Answer 2

or since the angle is negative, determine 360 -210

Answer 3

That ends up to be 150 ....which puts us in the second quadrant

Answer 4

and 150 is 30 away from 180, so 30 is our reference angle; -x,+y

Answer 5

Thank you
