Given the following vectors: A = 5.41 +8.71, B = 4.21 + 8.51, and C = 2.61 + 4.61 (a) Find the vector D, in unit vector notation, such that D+ 3A - SC + 4B = 0. X (b) Express your answer in part (a) in terms of magnitude and angle counterclockwise from the + x direction. (Indicate the direction with the sign of your answer.) Xat X O Solve the given expression and then substitute for the given vectors. Use the components of D to find its magnitude and direction Rook Dicturo it
