===================================

$\underline{SOLUTION}$ ➡

$Given, \\ \\ \tan A = \frac{3}{4} \\ \\ To \: find \: : \: \sin 2A = ?$

$We \: \: know \: \: that, \\ \\ \boxed{\sin 2A = \frac{2 \tan \: A}{1 + ( \tan \: A) {}^{2} }}$

$By \: using \: this \: formula ,\: \: we \: get ,\\ \\ \sin \: 2A \: = \frac{2 \times \frac{3}{4} }{1 + ( \frac{3}{4}) {}^{2} } \\ \\ = \frac{ \frac{3}{2} }{1 + \frac{9}{16} } \\ \\ = \frac{ \frac{3}{2} }{ \frac{16 + 9}{16} } \\ \\ = \frac{ \frac{3}{2} }{ \frac{25}{16} } \\ \\ = \frac{3}{2} \times \frac{16}{25} \\ \\ = \frac{24}{25}$

$\underline{ANSWER}$ ➡ $\sin \: 2A = \: \frac{24}{25}$
