if `|veca|=3,|vecb|=4,|veca-vecb|=5` then `|veca+vecb|=?`

If |veca|=5|vecb|=4 and |veca+vecb|=1 then |veca-vecb|= ?

If |veca|=2,|vecb|=3 and veca.vecb=4 , then |veca-vecb| is equal to

If veca and vecb are vectors such that |veca|=2,|vecb|=3 and veca*vecb=4 , then |veca-vecb| is equal to :

Statement 1 : If |veca | = 3, |vecb| = 4 and |veca + vecb| = 5 , then |veca - vecb|=5 . Statement 2 : The length of the diagonals of a rectangle is the same.

Statement 1 : If |veca | = 3, |vecb| = 4 and |veca + vecb| = 5 , then |veca - vecb|=5 . Statement 2 : The length of the diagonals of a rectangle is the same.

Statement 1 : If |veca | = 3, |vecb| = 4 and |veca + vecb| = 5 , then |veca - vecb|=5 . Statement 2 : The length of the diagonals of a rectangle is the same.

If |veca| = |vecb|=|veca+vecb|=1 then prove that |veca-vecb|=sqrt(3) .

If the three vectors veca,vecb,vecc are such that veca+vecb+vecc=vec0" and " |veca|=3,|vecb|=4,|vecc|=5 , then show that veca*vecb+vecb*vecc+vecc*veca=-25 .

If |veca|=3, |vecb|=1 and |veca+vecb|=|veca-vecb| , then |veca xx vecb| is:
