    If \[\sqrt{3}\tan 2\theta -3=0,\]then the angle \[9=\theta \]

    A)  \[30{}^\circ \]             

    B)  \[60{}^\circ \]

    C)  \[90{}^\circ \]             

    D)  None of these

    Correct Answer: A

    Solution :

    \[\sqrt{3}\tan 2\theta -3=0\] \[\,\Rightarrow \] \[\sqrt{3}\tan 2\theta =3\] \[\,\Rightarrow \] \[\tan 2\theta =\sqrt{3}=\tan 60{}^\circ \] \[\,\Rightarrow \]             \[2\theta =60{}^\circ \]    \[\theta =30{}^\circ \]
