Could I please have a detailed explanation of how to solve this vector displacement problem????

+y ii 20.00 50-0\" Hi. The three displacement vectors in the drawing have magnitudes ofA = 4.31 m. B = 5.75 m. and C = 4.17 m. Find the resultant {(a} magnitude and (b) directional angle) of the three vectors by means of the component method. Express the directional angle as an angle above the positive or negative 1:: axis which is less than 90
