The result of vectors make an angle of 90 withthe OA vector
tan90 is not defined. and direction of resultant vector isgiven by tanx=BSn theta/A+BCos theta
Hence A+BCos theta=0
           4+6Cos theta=0
                       theat=Cos-1(-2/3)
Feelfree toaskany doubt and if u find it helpful plz approve my answer.
