Question 1304a

Vectors II: Lines and Planes

Equation of a Plane from the Normal Vector

Question

The line

{l}

and plane

{p}

are given by

\begin{align*} &l: \mathbf{r} = \begin{pmatrix} - 3 \\ - 3 \\ 2 \end{pmatrix} + \lambda \begin{pmatrix} 5 \\ - 5 \\ 1 \end{pmatrix}, \; \lambda \in \mathbb{R}, \\ &p: \mathbf{r} \cdot \begin{pmatrix} 5 \\ 0 \\ 2 \end{pmatrix} = 43. \end{align*}

Find the acute angle,

{\theta,}

between the the line and the plane.

{\theta = }

{^\circ}
