\frac{a}{ \sin(a) }  =  \frac{b}{ \sin(b)  }
\frac{12}{ \sin(38) }  =  \frac{b}{ \sin(85) }
\frac{12}{ \sin(38) }  =  \frac{a}{ \sin(57) }
180 - (85 + 38) = 57
\frac{12}{ \sin(38) }  =  \frac{b}{ \sin(85) }
\sin(85)   \times  \frac{12}{ \sin(38) }  = b
\sin(57)   \times  \frac{12}{ \sin(38) }  = a
sorry for the order of steps
