A former A330/340 landing gear engineer writes...
I understood the question to mean - what is the angle of the bogie beam in relation to the gear leg? That is pretty much constant, allowing for a few aerodynamic effects. There is a small ram (the pitch trimmer) that gets the bogie in the right position, and more to the point, brings the angle down so that gears are in the correct position for the wheel bays. So the angle in question changes during the extension/retraction process.
BTW - the gear is a Messier Dowty design, proudly built in Gloucester!
I'll try and find the magic number for you, assuming that is the angle you are looking for.
