Step1) Okay you first need to figure out how much a 130m difference creates with a 400m wavelength. That would be 130/400 * 360 = 117 . The phase difference is then 117 degrees
Step2) The waves move from their sources already at a 90 degree phase difference so you need to subtract this phase difference together with the phase difference calculated in step one. 90 - 117 = - 27 degrees.
So the magnitude is 27 degrees
