When triangles are similar, we can set up a proportion to compare the sides. I will have the "left" side on the bottom of the fractions, and the side I am solving for on the top.

$\frac{y}{6} =\frac{13}{12}$

[Cross multiply]

12y = 78

y = 6.5

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.
