Let the given line
intersect at point P (a, b, g) to the plane x - y + z - 5 = 0 ...(ii)
\(\because\) P \((\alpha, \beta, \gamma)\) lie on line (i)
Also, P \((\alpha, \beta, \gamma)\) lies on plane (ii)
Hence, co-ordinate of required point = (2, -1, 2)
Now, find angle between line (i) and plane (ii)
If θ be the required angle, then
