Answer:
x = 2![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + (2
)² = 4²
x² + 8 = 16 ( subtract 8 from both sides )
x² = 8 ( take the square root of both sides )
x =
= 2![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
