The vectors \( \overrightarrow{u} \) and \( \overrightarrow{v} \) are given by the figure. Find cosine of the angle \(\varphi \) between \( \overrightarrow{u} \) and \( \overrightarrow{v} \). Help: Use the dot product of the given vectors.
\( \cos\varphi=\frac{13\sqrt{10}}{50} \)
\( \cos\varphi=\frac{970}{50} \)
\( \cos\varphi=\frac{3\sqrt{10}}{10} \)
\( \cos\varphi=\frac{\sqrt{10}}{5} \)
