Answer
$\sqrt 3$
Work Step by Step
The trigonometric ratios are as follows: $\sin \theta= \dfrac{opposite}{hypotenuse}$ ; $\cos \theta= \dfrac{Adjacent}{hypotenuse}$ and $\tan \theta= \dfrac{Opposite}{Adjacent}$
Now, $\tan \theta= \dfrac{Opposite}{Adjacent}$
and $\dfrac{\sin \theta}{\cos \theta}= \dfrac{-\sqrt 3/2}{(-1/2)}$
So, our required answer is: $\tan \theta=\sqrt 3$
