Question

Given vectors v and u, you know that (v)(u)=-2257.4the magnitude of the 2 vectors is 110 and 60.what is the angle between the two vectors?

Answer 1

The angle between two vectors a and b is equal to the formula

`cos\theta=(a\cdot b)/(\left|a\right|\cdot\left|b\right|)`

substitute given values

`cos\theta=(-2,257.4)/(110*60)`

angle θ=110 degrees
