Electricity and Magnetism problem?

A small magnetic dipole is kept at the origin in the x-y plane. One wire L1 is located at z= -a in the x-z plane with a current I flowing in the positive x direction. Another wire L2 is at z= +a in y-z plane with the same current I as in L1, flowing in the positive y direction. The angle ϕ made by the magnetic dipole with respect to the positive x-axis is .......... .

I am confused between 225 or 45 degree. I need to know which one of these two answers is correct and why.
