The Answer of Two vectors u and v are given. Find the angle correct to one decimal place (expressed in degrees) between u and v. $\mathbf { u } = \mathbf { i } + 2 \mathbf { j } - 3 \mathbf { k } , \mathbf { v } = \mathbf { j } + \mathbf { k }$

Two Vectors U and V Are Given u=i+2j−3k,v=j+k\mathbf { u } = \mathbf { i } + 2 \mathbf { j } - 3 \mathbf { k } , \mathbf { v } = \mathbf { j } + \mathbf { k }u=i+2j−3k,v=j+k

Two Vectors U and V Are Given $\mathbf { u } = \mathbf { i } + 2 \mathbf { j } - 3 \mathbf { k } , \mathbf { v } = \mathbf { j } + \mathbf { k }$
