Answer & Solution

Correct Answer

(D) \(\frac{1}{\sqrt{3}}\)

Step-by-step Solution

Detailed explanation

Line of intersection of planes \(x+y+z+1=0\) \(2 x-y+z+3=0\) eliminate y \(3 x+2 z+4=0\) \(x=\frac{-2 z-4}{3}\) put in equaiton (1) \(z=-3 y+1\) from (3) and (4) \(\frac{3 x+4}{-2}=-3 y+1=z\)…
