Answer 1

Answer: hello your question is poorly written below is the complete question

Find the angle between and if ⋅=3√2‖‖⋅‖‖.

(Use symbolic notation and fractions where needed. Give your answer in terms of . )

answer :

∅ = π / 6

Explanation:

V .W =
`(√(3) )/(2) || V ||. ||W||`

Hence

∅ = cos^-1 (
`((√(3) )/(2) || V ||. ||W||)/(||V||.||W||)`

∅ = cos^-1 (
`(√(3) )/(2)` )

∴ ∅ = π / 6
