Best ResponseYou've already chosen the best response.3You want the opposite. You have the angle and the adjacent. Which trig function, sine, cosine, or tangent, relate the angle measure to the opposite and the adjacent?

Best ResponseYou've already chosen the best response.3No. Look in my drawing above. First, the cosine does not have the opposite at all. In addition, you need one ratio that has both adjacent and opposite since we don't know anything about the hypotenuse.
