Answer:1, -4/7, 1

Explanation:

                           Direction cosine simply means the slant of any line relative to the origin considered.

                            Thus, to some origin K(0,0)

                                                              the line AB makes a slant

                                                                       cosФ= a/mod(AB)

                            mod(AB)=\sqrt{6^{2} +2^{2} +3^{2}

                                           =7

Thus cos angles are

                           1

                           -4/7

                            1
