Triangle ABC is a 45º 45º 90º triangle where the side across from the 90º angle is $$6\sqrt2$$

So the sides across from the 45º angles are $$\frac{6\sqrt2}{\sqrt2}=6$$

BC = 6

Triangle BCD is a 30º 60º 90º triangle where the side across from the 90º angle is 6

So the side across from the 30º angle is 6/2 = 3
