1. The problem statement, all variables and given/known data The truck is to be towed using two ropes. If the resultant force is to be 950 N, directed along the positive x axis, determine the magnitudes of forces FA and FB acting on each rope and the angle q of FB so that the magnitude of FB is a minimum. FA acts at 20° from the x axis as shown. 2. Relevant equations 3. The attempt at a solution I have no idea where to start because there is only 2 known values so i cant use sine law or cosine law. What's the first step ?
