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.
