Ok soo for the first one we're gonna use sine, (remember SOH CAH TOA) since we know the value of the hypotenuse.

Sin37° = x/9.3

0.6018=x/9.3

x= 5.59674

The last one we'll use cosine because we know the value of the side adjacent to 96°.

Cos42°=5.1/y

0.7431=5.1/y

y= 6.86272692

I assume it has you round your answers to the nearest tenth so the first one would be 5.6 and the second would be 6.9 .

Hope this helps!
