To find the value of \( x \) using the geometric mean, you typically need two numbers. The geometric mean of two positive numbers \( a \) and \( b \) is given by:
\[ \text{Geometric Mean} = \sqrt{a \cdot b} \]
If you can provide the two numbers or any additional relevant details from the image, I can help you calculate the geometric mean and find \( x \). Please share the necessary information!
