6 The plane \(\Pi\) has equation \(x + 2 y - 2 z = 5\). The line \(l\) has equation \(\frac { x - 1 } { 2 } = \frac { y + 1 } { 5 } = \frac { z - 2 } { 1 }\).
- Find the coordinates of the point of intersection of \(l\) with the plane \(\Pi\).
- Calculate the acute angle between \(l\) and \(\Pi\).
- Find the coordinates of the two points on the line \(l\) such that the distance of each point from the plane \(\Pi\) is 2 .
