If the lines ` (x-2)/(1)=(y-3)/(1)=(z-4)/(-k) ` and ` (x-1)/(k)=(y-4)/(2)=(z-5)/(1) ` are coplanar, then find the value of k.

Show that the lines (x-2)/(1)=(y-3)/(1)=(z-4)/(3)and(x-1)/(-3)=(y-4)/(2)=(z-5)/(1) are coplanar. Also, find the plane containing these lines.

If the straight lines (x-1)/(1)=(y-2)/(2)=(z-3)/(m^(2))and(x-3)/(1)=(y-2)/(m^(2))=(z-1)/(2) are coplanar, find the distinct real values of m.

Show that the lines (x+3)/(-3)=(y-1)/(1)=(z-5)/(5) and (x+1)/(-1)=(y-2)/(2)=(z-5)/(5) are coplanar .Al,so find the equation of the plane containing these two lines.

If the lines (x-1)/(-3) =(y-2)/(2k) =(z-3)/2 and (x-1)/(3k)=(y-1)/1=(z-6)/(-5) are perpendicular , find the value of k .

The straight lines (x-3)/(2)=(y+5)/(4)=(z-1)/(-13)and(x+1)/(3)=(y-4)/(5)=(z+2)/(2) are

If the lines (x-1)/(-3)=(y-2)/(2k) =(z-3)/2 and (x-1)/(3k) =(y-5)/1=(z-6)/(-5) are mutually perpendicular then k is equal to

The lines (x-2)/1=(y-3)/2=(z-4)/(-k)a n d=(x-1)/k=(y-4)/2=(z-5)/1 are coplanar if a. k=1or-1 b. k=0or-3 c. k=3or-3 d. k=0or-1

If the straight lines (x-1)/(2)=(y+1)/(lamda)=(z)/(2)and(x+1)/(5)=(y+1)/(2)=(z)/(lamda) are coplanar, find lamda and equations of the planes containing theses two lines.

Show that the lines (x-1)/(3)=(y-1)/(-1)=(z+1)/(0) and (x-4)/(2)=(y)/(0)=(z+1)/(3) intersect and hence find the point of intersection.
