Problem 3: While sliding a couch across a floor, Hannah and Andrea exert forces FH and FA on the couch. Hannah's force is due north with a magnitude of FĦ = 115 N and Andrea's force is 0 = 32° east of north with a magnitude of FA = 217 N. In this problem, use a coordinate system with positive y directed north and positive x directed east.
