Homework Statement
Determine the magnitude of the resultant force Fr=F1+F2 and its direction measured from the positive u axis.
Homework Equations
Law of Sines?
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.
