I dont need the steps

In an automobile safety test, a shoulder and seat belt exerts a force of 80.0 lb directly backward and a force of 72.0 lb backward at an angle of 18 below the horizontal on a dummy. If the belt holds the dummy from moving farther forward, what force did the dummy exert on the belt? 80.0 lb 72.0 lb Set up the problem by representing each force as a vector. using an angle given from standard position. LetA represent the 80.0 lb torce. and let 3 represent the 72.0 lb force. Vector l Magnitude l Standard-position Angle A lb B ID V the horiantal. The dummy exerted a force of lb, at an angle of (Round to one decimal place as needed.)
