Two radio antennas simultaneously transmit identical signals with a wavelength of 3.35 m. A radio several miles away in a car traveling parallel to the straight line between the antennas receives the signlas. If the second maximum is located at an angle of 1.28 degrees north of the central maximum for the interfering signals, what is the distance,d, between the two antennas?
Use the same formula that you would for a double-slit experiment with light. I think it's called Young's formula. See

The maxima occur and angles
sin theta = N *(lambda)/D
theta is the 1.28 degrees
N = 1 is the first order of diffraction pattern
Solve for the distance, D.
