limits - Evaluate $ lim_{xto infty^{-}}{frac{x}{3}}{left |arctan{frac{9}{x}}right |} $

I have a problem evaluating this limit. When I am trying it will come out 0. It is not good. Can you help how can I start with this limit?

$$
\lim_{x\to \infty^{-}}{\frac{x}{3}}{\left |\arctan{\frac{9}{x}}\right |}
$$
