In DeltaABC,vec(AB)=3hati+4hatk and vec(AC)=5hati-2hatj+4hatk . Length of the median drawn from A is ………………

In a Delta ABC, if vec(AB) = 3 hati + 4 hatk, vec(AC) = 5 hati + 2 hatj + 4hatk , then the length of median through A , is

The vectors vec(AB)=3hati+4hatk and vec(AC)=5hati-2hatj+4hatk are the sides of a triangle ABC. The length of the median through A is

If vectors vec(AB) = -3hati+ 4hatk and vec(AC) = 5hati -2hatj+4hatk are the sides of a Delta ABC , then the length of the median throught A is

If the vectors vec(AB)=3hati+4hatk and vec(AC)=5hati-2hatj-4hatk are the sides of a triangle ABC, then the length of the median through A is :
