Answer 2

Step-by-step explanation:

$\huge \boxed{\underbrace{\mathfrak {\underline  {\fcolorbox {black}{pink}{Answer}}}}}$

${  we \:know \:that.....   }$

${   tan\:30°=\frac{1}{\sqrt {3}}  }$

$\implies \frac{2tan30°}{1-tan^{2 }30°   }$

$\implies\frac {2×\frac{1}{\sqrt 3}}$

$\implies {\frac{\frac{2}{\sqrt {3}}}{1-\frac{1}{3}}     }$

$\implies { \frac{\frac{2}{\sqrt {3}}}{\frac{2}{3}}    }$

$\implies { \frac{2}{\sqrt {3}} × \frac{3}{2}    }$

$\implies {\sqrt {3}     }$

$\boxed{\blue {\sqrt {3}=tan\:60°     }}$
