If $\mathrm{Tan}22°+\mathrm{Tan}38°-\sqrt{3} =\mathrm{k} \mathrm{Tan}22° \mathrm{Tan}38°$ then $\mathrm{k}=$

$$\begin{gathered} \tan {22}^0+\tan {38}^0-\sqrt{3}=-\mathrm{k} \tan {22}^0 \tan {38}^0 \\ \tan ({22}^0+{38}^0)=\tan {60}^0 \\ \frac{\tan {22}^0+\tan {38}^0}{1-\tan {22}^0 \tan {38}^0}=\sqrt{3} \\ \tan {22}^0+\tan {38}^0=\sqrt{3}-\sqrt{3} \tan {22}^0 \tan {38}^0 \\ \tan {22}^0+\tan {38}^0-\sqrt{3}=-\sqrt{3} \tan {22}^0 \tan {38}^0 \end{gathered}$$
