If vec(A) = vec(B) + vec( C) and the magnitude of A, B and C are 5, 4

1.	If vec(A) = vec(B) + vec( C) and the magnitude of A, B and C are 5, 4 and 3 units respectively the angle between vec(A) and vec(B) is:
Answer» `cos^(-1) ((3)/(5))` `cos^(-1) ((4)/(5))` `((pi)/(2))` `SIN^(-1) ((4)/(5))` Answer :B
