please help me thanks if you do :') it would also be awesome if you could explain but its ok if you can't i guess. Find x

Answer:
[tex]x=4\sqrt{2}\ units[/tex]
Step-by-step explanation:
Theorem: In the right triangle the leg is the geometric mean of the hypotenuse and the segment of the hypotenuse adjacent to the leg.
Based on the theorem above,
[tex]x^2=2\cdot (2+6)\\ \\x^2=4\cdot 8\\ \\x^2=32\\ \\x=\sqrt{32}\ units\\ \\x=4\sqrt{2}\ units[/tex]
