Since there are  180°  in every triangle,   m∠J  =  180° - 73° - 52°   =   55°

 

Now we can use the law of sines to find the length of  HK .

 

\(\frac{HK}{\sin55°}\,=\,\frac{14}{\sin52°}\)

                                    Multiply both sides of the equation by  sin 55°

\(HK\,=\,\frac{14\sin55°}{\sin52°}\)

 

HK   ≈   14.6     yards
