2. Four dogs named Astro, Bam, Clifford, and Don play tug-of-war game with a toy. Astro pulls on the toy strongly with a force of 160.0 N in direction a=55° south of east, Bam pulls with an even much stronger force of 200.0 N in direction, b, 60° east of north. Clifford pulls with 140.0 N in the g direction 55° west of north. When Don pulls on the toy in such a way that his force balances out the resultant of the other three forces, the toy does not move in any direction. With how big a force and in what direction must Dug pull on the toy for this to happen?
