Identifica la recta cuyo ángulo con la recta \(s\) es igual a \(60^{\circ }\). \[ \begin{aligned}[t] s\colon x& = 2 + t, & \\y & = -1 - 2t, \\z & = 3 - t;\ t\in \mathbb{R} \\ \end{aligned} \]
\(\begin{aligned}[t] r\colon x& = t, & \\y & = -3 + t, \\z & = 1 + 2t;\ t\in \mathbb{R} \\ \end{aligned}\)
\(\begin{aligned}[t] q\colon x& = 1, & \\y & = -1 - t, \\z & = 3 + 2t;\ t\in \mathbb{R} \\ \end{aligned}\)
\(\begin{aligned}[t] p\colon x& = -5 - 2t,& \\y & = 2 + 4t, \\z & = 2 + 2t;\ t\in \mathbb{R} \\ \end{aligned}\)
