A pack of four velociraptors have caught a human running through their jungle. Each raptor grabs one limb and pulls as hard as it can. One raptor exerts a force of 50.0 N at an angle of 20.0 ̊. Another exerts a force of 30.0 N at an angle of 130.0 ̊, while a third exerts a force of 90.0 N at 160.0 ̊. If the meal remains stationary, i.e. the total force is 0, at what angle and with what force is the fourth raptor pulling? Note that force is a vector. Force is measured in units called Newtons which is abbreviated N.
