need help! this is matlab; follow directions exaclty please ! use only the most basic comands possible (through ch. 3)

Three forces are applied to a bracket as shown F; -700 N P-500 N 135 300 20 F-400 N Determine the direction angle of the total equivalent fore applied to the bracket The angle is in counter-clockwiso measuring from ex axis Assign forcon vectors as F1, F2, and F3. Also, FR for the total equivalent force vector and Th for the direction angle.
