Angle between their paths is 90+45 degree. The northwest plane went 410*2 miles from the airport and the eastern plane went 325*2 miles from the airport. This seems a fit for Law Of Cosines. You are looking for the side opposite of the known angle of 135 degrees, the angle between the planes' flight paths from the airport.
Angle: 135 degrees.
A side: 820 miles
Another side: 650 miles
Law Of Cosines: .
You know A and B, and you know also c. Solve for C.
