1. The problem statement, all variables and given/known data Determine the magnitude of the resultant force Fr=F1+F2 and its direction measured from the positive u axis. 2. Relevant equations Law of Sines? 3. The attempt at a solution I drew parallel lines and attempted to use the sine law, but I got two different answers. Here's the equations I used: Fr/sin100 = 200/sin50 Fr/sin100 = 300/sin30 Using these equations, I got two different answers for Fr, and didn't get any direction. Other than what I tried, I don't know what to do. We weren't taught how to find the magnitude from components or taught how to find direction.
