Find the magnitude and direction of the resultant R of the three vectors shown in Figure 1. The vectors have the following magnitudes: A = 5.0, B = 7.9, and C = 8.0. Express the direction of the vector sum by specifying the angle it makes with the positive x-axis, with the counterclockwise angles taken to be positive.
