One of the methods we can use to add these vectors is to resolve each one into a pair of vectors that lay on the north-south and east-west axes. The two vectors we are to add is a force of 65 N at 30°...One of the methods we can use to add these vectors is to resolve each one into a pair of vectors that lay on the north-south and east-west axes. The two vectors we are to add is a force of 65 N at 30° north of east and a force of 35 N at 60° north of west. Using trigonometry, we can resolve (break down) each of these vectors into a pair of vectors that lay on the axial lines (shown in red above).
