Best ResponseYou've already chosen the best response.1so, putting the value of tan theta let theta=x sec(^2)x=1+tan(^2)x =1+(3/4)^2 secx=5/4 so cos x=4/5

Best ResponseYou've already chosen the best response.0hint: If we divide both numerator and denominator by cos(\theta), we get: \[\Large \frac{{4\sin \theta  \cos \theta }}{{4\sin \theta + \cos \theta }} = \frac{{\frac{{4\sin \theta  \cos \theta }}{{\cos \theta }}}}{{\frac{{4\sin \theta + \cos \theta }}{{\cos \theta }}}} = \frac{{4\tan \theta  1}}{{4\tan \theta + 1}}\]

Best ResponseYou've already chosen the best response.0therefore, after a substitution, we can write this: \[\Large \begin{gathered} \frac{{4\sin \theta  \cos \theta }}{{4\sin \theta + \cos \theta }} = \frac{{\frac{{4\sin \theta  \cos \theta }}{{\cos \theta }}}}{{\frac{{4\sin \theta + \cos \theta }}{{\cos \theta }}}} = \frac{{4\tan \theta  1}}{{4\tan \theta + 1}} = \hfill \\ \hfill \\ = \frac{{\left( {4 \times \frac{3}{4}} \right)  1}}{{\left( {4 \times \frac{3}{4}} \right) + 1}} = ...? \hfill \\ \end{gathered} \]
