In order to find x, we first need to solve the ABC for side BC, then we can solve the right triangle from BC's length.
The left triangle is a 45-45-90. And the sides are:

y-y-y √(2) \\ so \: x √(2) \: = 6 √(2) \\ y(bc) = (6 √(2))/(√(2) ) = 6
for the right 30-60-90, the ratios are:

x - x √(3) - 2x \\ so \: 2x = 6 \\ x = 3
