Given that `vec(A)+vec(B)=vec(C )`. If `|vec(A)|=4, |vec(B)|=5` and `|vec(C )|=sqrt(61)`, the angle between `vec(A)` and `vec(B)` is

If vec(A)+vec(B)+vec(C)=0 and |vec(A)|=4,|vec(B)|=5 and |vec(C)|=1 , then the angle between vectors vec(B) and vec(C) is equal to

If vec(A) xx vec(B) = 0 and vec(B) xx vec(C ) = 0 , the angle between vec(A) and vec(C ) is :

Vectors vec(a), vec(b) and vec(c ) are such that vec(a) + vec(b) + vec(c ) = 0 and |vec(a)| = 3, |vec(b)| = 5 and |vec(c )| = 7 . Find the angle between vec(a) and vec(b) .

If vec(a) , vec(b) and vec(c ) be three vectors such that vec(a) + vec(b) + vec(c )=0 and |vec(a)|=3, |vec(b)|=5,|vec(C )|=7 , find the angle between vec(a) and vec(b) .

Let vec(a), vec(b) and vec(c) be three vectors such that vec(a) + vec(b) + vec(c) = 0 and |vec(a)|=10, |vec(b)|=6 and |vec(c) |=14 . What is the angle between vec(a) and vec(b) ?

If vec(A) + vec(B) = vec(C ) and A + B = C , then the angle between vec(A) and vec(B) is :

If vec(A) + vec(B) = vec(C ) and A + B = C , then the angle between vec(A) and vec(B) is :
