(x+1)/(1)=(y-4)/(1)=(z-5)/(2) " and " (x+3)/(3) =(y-2)/(5)=(z+5)/(4) Find angle between the lines .

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.

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.

Find the S.D. between the lines : (i) (x)/(2) = (y)/(-3) = (z)/(1) and (x -2)/(3) = (y - 1)/(-5) = (z + 4)/(2) (ii) (x -1)/(2) = (y - 2)/(3) = (z - 3)/(2) and (x + 1)/(3) = (y - 1)/(2) = (z - 1)/(5) (iii) (x + 1)/(7) = (y + 1)/(-6) = (z + 1)/(1) and (x -3)/(1) = (y -5)/(-2) = (z - 7)/(1) (iv) (x - 3)/(3) = (y - 8)/(-1) = (z-3)/(1) and (x + 3)/(-3) = (y +7)/(2) = (z -6)/(4) .
