If `veca,vecb,vecc` are unity vectors such that `vecd=lamdaveca+muvecb+gammavecc` then `lambda` is equal to (A) `([veca vecb vecc])/([vecb veca vecc])` (B) `([vecb vecc vecd])/([vecb vecc veca])` (C) `([vecb vecd vecc])/([veca vecb vecc])` (D) `([vecc vecb vecd])/([veca vecb vecc])`

The vectors veca and vecb are not perpendicular and vecc and vecd are two vectors satisfying : vecbxxvecc=vecbxxvecd and veca.vecd=0.

The vectors veca and vecb are not perpendicular and vecac and vecd are two vectors satisfying : vecbxxvecc=vecbxxvecd and veca.vecd=0.
