Question

Find the line of intersection and acute angle between these two planes. $\mathbf{r}=\left( \begin{matrix} 1 \ 2 \ 7 \ \end{matrix} ight)+\lambda \left( \begin{matrix} 1 \ 1 \ 0 \ \end{matrix} ight)+\mu \left( \begin{matrix} 1 \ 0 \ 1 \ \end{matrix} ight)$, $\lambda $, $\mu \in \mathbb{R}$ and $\mathbf{r}=\left( \begin{matrix} 1 \ 2 \ 7 \ \end{matrix} ight)+s\left( \begin{matrix} 1 \ 2 \ 4 \ \end{matrix} ight)+t\left( \begin{matrix} 0 \ 1 \ 1 \ \end{matrix} ight)$, $s$, $t\in \mathbb{R}$.

Accepted Answer

$\mathbf{r} = \begin{pmatrix} 2 \\ 7 \end{pmatrix} + d\begin{pmatrix} -2 \\ -1 \\ -3 \end{pmatrix}$
