1. The problem statement, all variables and given/known data Two force vectors are shown in the figure (not drawn to scale), and the total force vector C is the sum of A and B:C=A+B. If the magnitude of the total force is C = 80 N and its direction is specified by the angle measured from +x axis to be θC = −110˚, find B and φ for the force vector B. 2. Relevant equations Cx= Ax+ Bx Cy= Ay+ By C= sqrt(Cx^2+Cy^2)? tanθc=Cy/Cx? 3. The attempt at a solution Ax=-150cos30=-130 Ay=150sin30=75 Cx=80sin(-110)=-75.2 Cy=80cos(-110)=27.4 Cx= Ax+ Bx -75.2= -130 + B > B= 54.8 27.4= 75 + B > B=-47.6 Not sure if I'm doing this right.
