Current Attempt in Progress

One long wire lies along an $x$ axis and carries a current of $57$ A in the positive $x$ direction. A second long wire is perpendicular to the $xy$ plane, passes through the point $),$ and carries a current of $56$ A in the positive $z$ direction. What is the magnitude of the resulting magnetic field at the point $(0,0\mathrm{.}70m,0)?$
