\({\mathrm{L}}_{1}=\frac{x-1}{1}=\frac{y-2}{-1}=\frac{z-1}{2},{L}_{2}:\frac{x+1}{-1}=\frac{y-2}{2}=\frac{z}{1}\)

Let the line \({\mathrm{L}}_{3}\) passes through the point \((\alpha ,\beta ,\gamma )\) perpendicular to \({L}_{1}&{L}_{2}\) and \({L}_{3}\) intersect line \({L}_{1}\) then \(|5\alpha -11\beta -8\gamma |\).
