Let ABCD is parallelogramogram where `A = (1,2,4) , B = (8,7,9) and D = (6,1,5)`. Find direction cosines of line AC.

(A) find the direction-cosines of the lines joining the points : (-1, -1, -1) and (2,3,4) (b) Find the direction ratios and direction cosines of the vector joining the points (4,7,2) and (5,11,-4). (c ) Find the direction cosines of a line segment joining the points A (2,5,7) and B (3,2,9) .

The direction ratios of a line are 1,-2,5 , find the direction cosines of the line.
