Find the distance between the foci of the following hyperbola. \[ H\colon \frac{\left (x + 1\right )^{2}} {16} -\frac{\left (y + 5\right )^{2}} {9} = 1 \]

Find the angle between two lines and round your answer to the nearest minute. \[ \begin{aligned}p\colon x& = 2 - t , & \\y & = 3t , \\z & = 1 ;\ t\in \mathbb{R} \\ \end{aligned}\qquad \qquad \begin{aligned}q\colon x& = 2s, & \\y & = 4s , \\z & = 1 - s;\ s\in \mathbb{R} \\ \end{aligned} \]

Given points \(A = [0;1;2]\), \(B = [1;2;0]\), \(C = [1;2;3]\), find the angle between the lines \(AB\) and \(AC\). Round your answer to the nearest degree.

Find the angle between the \(x\)-axis and the line \(p\). \[ \begin{aligned}p\colon x& = 2 - t, & \\y & = 3t, \\z & = 1;\ t\in \mathbb{R} \\ \end{aligned} \] Round your answer to the nearest minute.
