Question

answer me fast I want the answer fadt​

Answer 1

⭐Given:

• A=i+j+k

• B= -2i-2j-2k

⭐To Find:

• Angle between these two vectors=?

⭐Solution:

Since,

we know that,

Ā. B=AB cos theta... (Formula)

: . (i+j+k) . (-2i-2j-2k) =√3×2√3×cos theta

: . cos theta= -6/6

: . cos theta= -1

: . Theta = 180°

Therefore,

Angle between the two vectors is 180°
