If a line with direction ratios(2,2,1) intersects the line x−73=y− – InterviewSolution

1.	If a line with direction ratios(2,2,1) intersects the line x−73=y−52=z+31 and x−12=y+14=z+13 at A and B then AB=.
Answer» If a line with direction ratios $(2, 2, 1)$ intersects the line $\frac{x - 7}{3} = \frac{y - 5}{2} = \frac{z + 3}{1}$ and $\frac{x - 1}{2} = \frac{y + 1}{4} = \frac{z + 1}{3}$ at A and B then AB=.
