The x-component of vector A is:

A_{x} = Acos(60°)

The y-component of A is:

A_{y} = Asin(60°)

Therefore, Vector A is:

A = Acos(60°)i + Asin(60°)j

A = (4)cos(60°)i + (4)sin(60°)j = 2i + 3.46 j

Find vector *C*? such that *A*? +*B*? +*C*? =0? . Write your answer in component form.

Express your answer in terms of the unit vectors *i*^ and *j*^. Use the 'unit vector' button to denote unit vectors in your answer. Express the coefficients using two significant figures.
