1. The problem statement, all variables and given/known data You are given a vector in the xy plane that has a magnitude of 85.0 units and a y component of -50.0 units The two possibilities for its x component are +68.74 and -68.74 Assuming the x component is known to be positive, specify the vector which, if you add it to the original one would give a resultant vector that is 70.0 units long and points entirely in the -x direction. Magnitude = ? Direction = ? degree 2. Relevant equations 3. The attempt at a solution I found that the magnitude was 147.47 by [(-138.74)^2+(50)^2]^(1/2) or 147.47. The problem is I can't geet the direction in degrees. I did arcsin(50/147.47)=19.82 but that is not right. Please help thanks!
