The value of x is 4.
Solution:
The reference image for the geometric mean of the right triangle is given below.
b = x, c = 6 and d = 2
By the property of similar right triangle:
![{b}^(2)={d} \cdot({c}+{d})](https://img.qammunity.org/2021/formulas/mathematics/middle-school/aycgwgure230bc6iylr6dqvum76uefrqtm.png)
![{x}^(2)={2} \cdot({6}+{2})](https://img.qammunity.org/2021/formulas/mathematics/middle-school/p0brvlravckxcwwkn408to9v659y3sunbz.png)
![{x}^(2)={2} \cdot(8)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/clm492gmrzm81ha089gfj2efiis2fnhlzo.png)
![{x}^(2)=16](https://img.qammunity.org/2021/formulas/mathematics/middle-school/9xk2zlvorhmlf57l6r7t7p21o8k3toodv9.png)
Taking square root on both side of the equation.
x = 4
Hence the value of x is 4.
