If the lines x-11=y-22=z+31 and x-a2=y+23=z-31 intersects at the point P, then the distance of the point P from the plane z=a is :

Question

If the lines

\frac{x - 1}{1} = \frac{y - 2}{2} = \frac{z + 3}{1}

and

\frac{x - a}{2} = \frac{y + 2}{3} = \frac{z - 3}{1}

intersects at the point

P

, then the distance of the point

P

from the plane

z = a

is :
