# Find the angle be

Answer :

Given: and So,        We know that where θ is the angle between According to the question our equation becomes, …(i)

Now, = (5.(-1)) + (0).(1) + (1).(5)

= -5 + 5

= 0

Magnitude of  Magnitude of  Now, putting the values in eq. (i), we get 0 = √26 √30 cos θ

cos θ = 0 So, the angle between Now, we have to find the vector which is perpendicular to A vector perpendicular to both    Rate this question :
