Forces of 10 N, 12 N and 20 N act in the same plane on an object in the directions west, 30" west of north, and north respectively. Determine, from the components of the forces, the resultant force.

Forces of 1 N, 2 N, 3 N, 4 N and 5 N act in the same plane on an object in the directions north, north-east, east, 60" west of south, and due west respectively. Determine, by considering the components of the forces, the resultant force.
