Two forces are applied to a tree stump to pull it out of the ground. Force Fa has a magnitude of 2240 newtons and points 34 degrees south east, while Force Fb has a magnitude of 3160 newtons and points due south. Using the component method, find the magnitude and direction of the resultant force Fa + Fb that is applied to the stump. Specify the direction with respect to due east.
