Astronauts on the space shuttle use radar to determine the magnitudes and direction cosines of the position vectors of two satellites A and B. The vector ra from the shuttle to satellite A has magnitude C km, and direction cosines cos a= D, cos ß = E, cos y = F. The vector ra from the shuttle to satellite B has magnitude G km and direction cosines cos a = H, cos B = 1, cos y = J. What is the distance between the satellites?
