Oh, "coordinates". However, neither (6, 19) nor (.6, .19) is on the unit circle because neither nor is equal to 1. (.6, .8)... and quarantines were given like (6,19) (might have been (.6,.19) or something)ison the unit circle because .

Is that or ? And what was theand the answers given where something like √19/6.question?

If corresponds to a radius of the unit circle passing through (.8, .6) thenI know its not alot to work with but how do you solve something that gives quardanates on a unit circle and an equation?

1)

2)

3)

4)

5)

6) or approximately 1.667

That's the best I can do.
