Answer:
8 - 
Step-by-step explanation:
For this problem you have to use the 45-45-90 triangle theorem and 30-60-90 theorem. 
For 45-45-90, the isosceles sides = 4, so the hypotenuse of the 30-60-90 triangle is 4 times 2, which is 8. If x is 8, then since y is the side across from the 60 angle, y is  . Since this really can't be simplified after y is subtracted from x, the final answer is just 8 -
. Since this really can't be simplified after y is subtracted from x, the final answer is just 8 -  .
