Best ResponseYou've already chosen the best response.0so your first move would be to find the length of the hypotenuse and then use the trig identities to solve for the sin cos and tan!

Best ResponseYou've already chosen the best response.0ok, to find the hypotenuse, you use the pythagorean theorem. you know how to do that?

Best ResponseYou've already chosen the best response.0right, so you find c, which is the hypotenuse, by using a=3 and b2 in that equation. Then you can use the trig in my picture to solve!

Best ResponseYou've already chosen the best response.0So adjacent would be 2 and Opp would be 3?

Best ResponseYou've already chosen the best response.0right! then use just use the equations in my first picture to solve it out!

Best ResponseYou've already chosen the best response.0Absolutely! Can you now find the sin, cos, and tan? dw:1442518693365:dw
