Given:
[tex]\tan (\frac{19\pi}{12})[/tex][tex]\pi=180\text{ degre}es[/tex]So:
[tex]\begin{gathered} \tan (\frac{19\times180}{12}) \\ =\tan (\frac{3420}{12}) \\ =\tan (285) \\ =-3.732 \end{gathered}[/tex]Check the value for all opction.
(a)
[tex]\begin{gathered} =\frac{3+\sqrt[]{3}}{-3+\sqrt[]{3}} \\ =\frac{3+1.73205}{-3+1.73205} \\ =-3.732 \end{gathered}[/tex]So the first opction is equal to -3.732
