Let's start by identify a 30-60-90 triangle
If we compare those two traingles we can stablish the following relation:
[tex]\begin{gathered} a\sqrt[]{3}=6\sqrt[]{3} \\ \end{gathered}[/tex]
Therefore, a=6
u is the opposite side to the 90° angle, therefore
[tex]\begin{gathered} u=2a \\ u=2\cdot6 \\ u=12 \end{gathered}[/tex]
on the other hand, v is the opposite side to the 30° angles, so
[tex]\begin{gathered} v=a \\ v=6 \end{gathered}[/tex]
