The points \(A = [0;5;0]\), \(B = [5;5;0]\), \(C = [5;0;0]\), \(D = [0;0;0]\) define the cube \(ABCDEFGH\). Find the angle between the lines \(BF\) and \(AC\). Round your answer to the nearest minute.

Find the distance from the point \(A = [0;1;-3]\) to the point \(B = [-1;3;0]\).

Find the distance between the point \(A = [1;0;1]\) and the line \(p\). \[ \begin{aligned}p\colon x& = 2, & \\y & = 3t, \\z & = 1 - t;\ t\in \mathbb{R} \\ \end{aligned} \]

Find the distance between two parallel lines \(p\) and \(q\). \[ \begin{aligned}p\colon x& = 2, & \\y & = 3t, \\z & = 1 - t;\ t\in \mathbb{R} \\ \end{aligned}\qquad \qquad \begin{aligned}q\colon x& = 3, & \\y & = 6s, \\z & = 1 - 2s;\ s\in \mathbb{R} \\ \end{aligned} \]
