The path difference between two waves is 5m. If the wavelength of the waves emitted by the two sources is 4m, what is the phase difference

where is the circuit diagram ?

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
