Best ResponseYou've already chosen the best response.0now you can take any trig ratio you want, just remember what quadrant you are in to make sure to know if it is positive or negative

Best ResponseYou've already chosen the best response.0You can't leave a radical in the denominator. You would have to multiply the 2/sqrt5 by sqrt5/sqrt5
