We are using The Law of Sines here

 

sinx / 38   = sin35 / 22      multiply both sides by 38

 

sin x   =   (38/22)sin35

 

Take the sine inverse

 

arcsin [   (38/22)sin35 ]   = x  ≈  82.2°

 

 

For the second one, we have

 

g / sin (74)  =  54/sin (58)      multiply both sides by sin(74)

 

g  = sin(74)* 58 / sin (58)   ≈  65.7

I think you accidently wrote 58 instead of 54 on the very last line.

 

g  = sin(74) * 54 / sin (58)

 

So..  g ≈ 61.2      smileysmiley
