Cuando el vector está dado por sus componentes rectangulares o cartesianas:
![\[\begin{gathered}
\tan \left( \beta \right) = \frac{{{A_y}}}{{{A_x}}} \hfill \\
{A_x} = \frac{{{A_y}}}{{\tan \left( \beta \right)}} \hfill \\
{A_x} = \frac{4}{{\tan \left( {23} \right)}} \hfill \\
{A_x} = 9.42 \hfill \\
\end{gathered} \] \\](https://tex.z-dn.net/?f=%5C%5B%5Cbegin%7Bgathered%7D%0A++%5Ctan+%5Cleft%28+%5Cbeta++%5Cright%29+%3D+%5Cfrac%7B%7B%7BA_y%7D%7D%7D%7B%7B%7BA_x%7D%7D%7D+%5Chfill+%5C%5C%0A++%7BA_x%7D+%3D+%5Cfrac%7B%7B%7BA_y%7D%7D%7D%7B%7B%5Ctan+%5Cleft%28+%5Cbeta++%5Cright%29%7D%7D+%5Chfill+%5C%5C%0A++%7BA_x%7D+%3D+%5Cfrac%7B4%7D%7B%7B%5Ctan+%5Cleft%28+%7B23%7D+%5Cright%29%7D%7D+%5Chfill+%5C%5C%0A++%7BA_x%7D+%3D+9.42+%5Chfill+%5C%5C+%0A%5Cend%7Bgathered%7D+%5C%5D+%5C%5C+ "\[\begin{gathered}
