Use the component method to add the vectors A and B shown in the figure. Both vectors have magnitudes of 3.55 m and vector A makes an angle of
$θ = 28.5°$ with the x axis. Express the resultant A + B in unit-vector notation.

I don't understand how my answer is wrong.

Isn't it $A + B = (3.12)i + (1.69)j $ ?

Seeing as we don't know what vector B is we cannot help you much.
