Why is the force Fd pointing downwards? By force equilibrium, shouldnt  it be 3 + Fd = 9 Fd = 6kN, thus pointing upwards?

The two structural members, one of which is in tension and the other in compression, exert the indicated forces on joint O. Determine the magnitude of the resultant Rof the two forces and the angle e which R makes with the positive x-axis. The angle e is measured counterclockwise from the positive x-axis. 4.5 kN 2.0 kN 37° 65 Answers: R = i kN i
