Angle c is arcsin (3/5)    (remember sin is  opp/hyp)   = 36.87 degrees

 

Similar here   angle r     =  arcsin (30/40) = 48.59 degrees

We can use the arctangent here

 

arctan (3/4)  = C ≈  36.87°

 

 

Second one..we know the opposite side to R and the hypotenuse...so....we can use the arcsin

 

arcsin (30/40)  = R ≈ 48.59°

 

 

cool cool cool
