Vector A has components (5,6) and vector B has components (-12, 3). What is the direction of the vector C = 2A - B

22.24° to the positive x-axis.

Given vectors:

A (5, 6)

B (-12, 3)

C = 2A - B             ------------(i)

First let's represent the two vectors in unit notation as follows;

A = 5 i + 6 j

B = -12 i + 3 j

Now substitute these vectors into equation (i) as follows;

C = 2(5 i + 6 j) - (-12 i + 3 j)

C = 2(5 i + 6 j) + (12 i - 3 j)

C = 10 i + 12 j + 12 i - 3 j                   [collect like terms]

C = 10 i + 12 i + 12 j - 3 j

C = 22 i + 9 j                         ----------------(ii)

The direction, θ, of vector C can be calculated as follows;

θ = tan⁻¹()

θ = tan⁻¹(0.409)

θ = 22.24°

Since both the x and y components of vector C are positive, the direction of the vector is 22.24° to the positive x-axis.
