The diagram below shows two vectors, $$A$$ and $$B$$, and their angles relative to the coordinate axes as indicated. DATA: $$\mathrm{a}=46.1^{?}?=59.2^{?}?\mathrm{A}?=2.1\mathrm{cm}$$. The vector $$\mathbf{A}?\mathbf{B}$$ is parallel to the $$?\mathbf{x}$$ axis (points due West). Calculate the $$y?$$ Since the sum vector (A-B) has no $$y?$$ component, vector A must have the same y-component as vector B. As shown, 'east' is for $$+x$$, and 'north' for $$+y$$, thus the answer can be negative.
