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
