Vector Subtraction

Two vectors A and B are shown in the x-y plane. Vector A has a magnitude of 5 m and makes an angle of 55° with the positive x-axis; vector B has a magnitude of 2 m and makes an angle of 33° with the negative x-axis. (See the figure above.) Vector C (not shown in the diagram) is the difference of A and B (C = A - B).

If you enter an expression, use degrees as arguments for sin and cos, rather than radians.

What is the magnitude of C?

|C| = m
