![### Geometry Problem:
#### Question:
Find and solve for \( x \) in the figure below:
#### Diagram:
A right triangle ABC is depicted with the following details:
- Side AD measures 3 units.
- Side DB measures 9 units.
- Point D is perpendicular to side AB, making triangle ADC a right triangle.
#### Options:
- A. \( x = 3\sqrt{5} \)
- B. \( x = 3\sqrt{6} \)
- C. \( x = \frac{9}{\sqrt{5}} \)
- D. \( x = 4 \)
From the given options, one has been marked with an 'X', indicating it's the incorrect choice.
#### Explanation:
To solve for \( x \), consider the right triangle properties and the use of geometric formulas appropriate for the problem statement, such as the Pythagorean Theorem, trigonometric ratios, or specific properties of right triangles. Use these principles to find \( x \).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4904ad93-6dcc-43fa-9122-8f69394907f2%2F85eae283-4992-49e6-844d-b97792232c9c%2Fjb2hha_processed.jpeg&w=3840&q=75)
