Dear Imran,

you can write direction cosines in terms of vectors eg. for a line with direction cosine a,b,c we have in vector notation ai+bj+ck(i,j,k are usual unit vectors)

so write both lines in vector notation and then take there cross product that will correspond to perpendicular vector now you can write there direction ratios or cosines.
