Three forces are applied to an object, as indicated in the drawing. Force 1 has a magnitude of 27.0 newtons (27.0 N) and is directed 30.0° to the left of the +y axis. Force 2 has a magnitude of 20.0 N and points along the +x axis. What must be the magnitude and direction (specified by the angle in the drawing) of the third force 3 such that the vector sum of the three forces is 0 N?
