Besides stability, one reason for putting dihedral in a wing is to
provide adequate clearance for the wing tips and engines should the
aircraft land with some bank angle.  The 777, with its very large
diameter engines and large span probably has large amounts of
dihedral because of this clearance issue.  Extra dihedral gets the
engines a little higher off the ground enabling the plane to meet
clearance requirements with shorter, lighter landing gear.
