    \[\sin A = \frac {opp}{hyp} \]

    wouldn't i do the sin- since i don't have the angle for A

    You don't need to have the angle to find the sin of A. Sin of A would be its opposite side over the hypotenuse.

    Determining angle A won't really help.

    You are right. You don't have the angle, you are going to calculate that just like you said with sin-, but you do have the lengths of the side opposite angle A and the hypotenuse.

    \(\Huge \sin A = {20 \over 29}\)
