there are a few ways to do this. You can use the Pythagorean theorem to solve for the hypotenuse of the triangle and then use SOHCAHTOA. Or you can use a trig ratio to solve for Θ and go from there.|dw:1440081411548:dw|

ok, so from Θ, the adjacent side is 1, the opposite is -1, and the hypotenuse is √2. Can you tell the values of sin Θ, cos Θ and tan Θ now?
