1. The problem statement, all variables and given/known data I've got to determine the resultant(R) and the angle between the x-axis and the line of action of the resultant. My picture(don't know how to draw on here), is two vectors, with one pointing into quad 1, and the other into quad 2. For the right one, It is given that you have a 3y/4x/5hyp triangle for this vector. And, the magnitude is 240N. The vector comes directly out of the orgin, similar to a 45 deg angle. Vector 2 is given to be a magnitude of 180 N, and in a 1x/2y/3hyp triangle. 2. Relevant equations Using sin(90)/5 = sin(x)/3 I found the angle from the pos x axis to the vector to be 36 degrees.(vector 1) R^2 = F1^2 + F2^2 + 2F1F2cos(x) Law of sines/Law of cosines 3. The attempt at a solution If you can even understand this problem, I'd like some help as to where to start. I'm not sure if my geometry/trig is right. I've made a parallelogram around the vectors. Any help would be great.
