Answer: x=
8√(2)

Explanation:

There are special right triangles in this! First, you need to find out what I am saying.

45-45-90 triangle

The bottom triangle has angles measures of 45, 45, and 90 degrees. There is a theorem that states that the two legs are equal, and the hypotenuse is leg×
√(2).

Plugging it in will give you leg lengths of
4√(2).

Plug in that number into the side that connects with our next very special triangle:

30-60-90 triangle

Another theorem states that the hypotenuse is shorter leg times 2, the longer leg is shorter leg times
√(3).

Great! We have the shorter leg. Now we need to find the hypotenuse. Multiply
4√(2) by 2, and you get
8√(2). That is x!

The final answer to this problem is: x=
8√(2)

Hope this helped a lot!
