Answer:
![x = 2\sqrt{11}](https://tex.z-dn.net/?f=%20x%20%3D%202%5Csqrt%7B11%7D%20)
Step-by-step explanation:
AD = 4
AC = 11
DC = 11 - 4 = 7
First, find BD using the right triangle altitude theorem:
![BD = \sqrt{AD*DC}](https://tex.z-dn.net/?f=%20BD%20%3D%20%5Csqrt%7BAD%2ADC%7D%20)
Plug in the values
![BD = \sqrt{4*7}](https://tex.z-dn.net/?f=%20BD%20%3D%20%5Csqrt%7B4%2A7%7D%20)
![BD = 2\sqrt{7}](https://tex.z-dn.net/?f=%20BD%20%3D%202%5Csqrt%7B7%7D%20)
Use pythagorean theorem to find x:
x² = AD² + BD²
Plug in the values
![x^2 = 4^2 + (2\sqrt{7})^2](https://tex.z-dn.net/?f=%20x%5E2%20%3D%204%5E2%20%2B%20%282%5Csqrt%7B7%7D%29%5E2%20)
![x^2 = 4^2 + (2\sqrt{7})^2](https://tex.z-dn.net/?f=%20x%5E2%20%3D%204%5E2%20%2B%20%282%5Csqrt%7B7%7D%29%5E2%20)
![x^2 = 16 + (4*7)](https://tex.z-dn.net/?f=%20x%5E2%20%3D%2016%20%2B%20%284%2A7%29%20)
![x^2 = 16 + 28](https://tex.z-dn.net/?f=%20x%5E2%20%3D%2016%20%2B%2028%20)
![x^2 = 44](https://tex.z-dn.net/?f=%20x%5E2%20%3D%2044%20)
Take the square root of both sides
![\sqrt{x^2} = \sqrt{44}](https://tex.z-dn.net/?f=%20%5Csqrt%7Bx%5E2%7D%20%3D%20%5Csqrt%7B44%7D%20)
![x = \sqrt{44}](https://tex.z-dn.net/?f=%20x%20%3D%20%5Csqrt%7B44%7D%20)
![x = \sqrt{4 * 11}](https://tex.z-dn.net/?f=%20x%20%3D%20%5Csqrt%7B4%20%2A%2011%7D%20)
![x = 2\sqrt{11}](https://tex.z-dn.net/?f=%20x%20%3D%202%5Csqrt%7B11%7D%20)
