Round your final answer to the nearest tenth, if necessary.

We can use the Law of Sines to answer this

 

sin R  / 30   = sin 96° / 54        multiply both sides by  30

 

sin R  = 30 * sin 96° / 54

 

To find  "R"....we  need to use the  sine inverse   ( arcsin )

 

arcsin [ 30 * sin (96°) / 54  ]  =  "R"   ≈ 33.54°
