If the straight lines `x=-1+s ,y=3-lambdas ,z=1+lambdasa n dx=t/2,y=1+t ,z=2-t ,` with paramerters `sa n dt ,` respectivley, are coplanar, then find `lambdadot`

If the straighat lines x=1+s,y=-3-lamdas,z=1+lamdas and x=t/2,y=1+t,z=2-t with parameters s and t respectively, are coplanar, then lamda equals (A) -1/2 (B) -1 (C) -2 (D) 0

If the straight lines (x-5)/(5m)=(2-y)/(5)=(1-z)/(-1)andx=(2y+1)/(4m)=(1-z)/(-3) are perpendicular to each other, find the value of m.

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.

The equation of two straight lines are (x-1)/2=(y+3)/1=(z-2)/(-3)a n d(x-2)/1=(y-1)/(-3)=(z+3)/2dot Statement 1: the given lines are coplanar. Statement 2: The equations 2x_1-y_1=1,x_1+3y_1=4a n d3x-1+2y_1=5 are consistent.

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.
