A. the x component of vector A = - A cos 30 = - 50 cos30 = -50X.866 = -43.3 minus sign is because the direction is towards - x direction.
B y component = A sin30 = 50sin30 = 25
C: y component = -49 sin28 = -49*.469 = -23 Ans
D: vector D makes an angle of 73deg with - x axis,
so x component = - 73cos73 = -21.3
