I have a hard time solving math task, which I have to do with vectors. I will post the photo of the triangle given in the task. Currently I am solving quite a lot of exercises with vectors, however I feel lost on this one.
The task:
Right triangle $ABC$, $\angle C$ is 90 degrees. The cosine of acute angle $\angle A$ is $\frac{\sqrt6}{3}$. Find angle between medians $CD$ and $BE$.
