Four vectors A,B,C ,D and are shown (not to scale). Vector A has magnitude 23.0 and acts at an angle of 14.7 degrees with respect to the positive x axis. Vector B has magnitude 15.0 and acts at an angle of 61.4 degrees with respect to the positive x axis. What are the magnitude and direction of the resultant vector R , when the parallelogram law is applied to A and B?
