1. Two ariels are 2.50m apart, and both are receiving the same radio signal with a frequency of 125 MHz. The phase difference between themis measured at 114 degrees. Calculate the path difference between the two ariels.
The ariel in the previous question which recieves the signal first is directly North of one which recieves the signal slightly later. What are the possible bearings of the transmitter from the recieving ariels? You may assume that the transmitter is many kilometers from the recieving ariels, and therefore that the path of the waves travelling to tue teo recievers are effectively in parrallel when measured in the bicinity of the recieving airiels.
2. A phase difference of 360 deg corresponds to a path difference of 1 wavelength... 180 deg is λ/2 etc. etc.

IM oblivious as to what to do for the second part, i got 0.76 for the path difference but i dont know what to do about the bearing

the aerials are located with one due north of the other... If the transmitter was to their east or west the path difference would be zero, right?
so what angle would give the required path difference? Probably it'll help if you sketch a diagram

I did draw a diagram, i still dont know how to work out the actual angle
