I know how to do this problem, but I am having a difficult time figuring out the distance . I thought that from wire 1 to P2 the distance is 45 cm, and the distance from wire 2 to the p2 the distance is 35 cm. However, I believe I am wrong, can someone please explain o me where my mistake it .

Question: Two long, straight parallel wires are 10.0 cm apart and carry 3.80 A currents in the same direction. Find the magnitude of the magnetic field at point P2 , 35.0cm to the right of P1.

I am not certain of the orientation of the wires and P2, are they all in the same plane? Where is P1?
they are in the same plane
I1-----P1------I2---------P2
The current are both out of the plane.
