- Verify that the lines \(\mathbf { r } = \left( \begin{array} { r } - 5
3
4 \end{array} \right) + \lambda \left( \begin{array} { r } 3
0
- 1 \end{array} \right)\) and \(\mathbf { r } = \left( \begin{array} { r } - 1
4
2 \end{array} \right) + \mu \left( \begin{array} { r } 2
- 1
0 \end{array} \right)\) meet at the point (1,3,2). - Find the acute angle between the lines.
