Given: three forces act on a particle P. Force A has a magnitude of 55lbs and acts 30 degrees CCW from the x-axis. Force B has a magnitude of 70 lbs and acts along a ray from point P with a slope at 1/-4. Force C has a magnitude of 55 lbs lbs and acts straight left. Add the three vectors to find the magnitude of the resultant force R and the angle makes with the positive a-axis 0.
