If the lines<span

Answer :

Given equations are –


L1:


It can also be represented in vector form.


L1:


And L2:


It can also be represented in vector form.


L2:


For lines to be perpendicular, the dot product of their direction vectors must be zero.



-3k – 2k + 10 = 0


-5k = -10


k = 2


equation of line can be rewritten as –


L1:


And L2:


Equation of plane containing the lines is given by -


= 0


(x – 1) (-20 – 2) – (y – 2) (-15 – 4) + (z – 3) (-3 + 8) = 0


-22x + 19y + 5z = 31


Required equation of the plane is: -22x + 19y + 5z = 31
