$\sin A = \frac {opp}{hyp}$

3. catgirl17 Group Title

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

4. ParthKohli Group Title

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.

5. catgirl17 Group Title

oh okay then

6. ParthKohli Group Title

Determining angle A won't really help.

7. pfenn1 Group Title

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.

8. ParthKohli Group Title

$$\Huge \sin A = {20 \over 29}$$
