The x vector component of a displacement vector vec$(r)$ has a magnitude of $84\mathrm{.}6m$ and points along the negative $x$ axis. The $y$ vector component has a magnitude of $148m$ and points along the negative $y$ axis. Find $($a$)$ the magnitude and $($b$)$ direction of vec$(r).$ Specify the direction as a positive angle with respect to the negative $x$ axis.
