Referring to the vectors in the figure, express the sum A + B + C in unit vector notation.
I'm not sure if it wants me to add Dy, I've tried it both times and masteringphysics won't take either answer.
The Attempt at a Solution
I'm assuming we need Ax, Ay, Bx, By, Cy, Cx and add Dy.
Ay= sin40 x 1.5 = .96
Ax= Cos40 x 1.5 = 1.15
Bx= Cos19 x 2.0 = 1.89
By= Sin19 x 2.0 = .65
Cx= Cos25 x 1 = .906
Cy= sin25 x 1 = .42
The sum would be (3.946, 3.53)?
Would appreciate any help on this problem, I'm not really quite sure what I'm missing or if I did the trig wrong.
