Vector A= (10, 40 degrees above negative x-axis) and vector B= (20, 30 degrees below positive x-axis). What is the magnitude of A + B?Vector A= (10, 40 degrees above negative x-axis) and vector B= (20, 30 degrees below positive x-axis). If vector C is chosen such that A + B + C = 0, what is the direction of vector C? Give your answer in degrees, as a positive angle measured counter-clockwise from the positive x-axis
