Find the value of x to the nearest hundredth
### Problem Statement:

Find the value of \( x \) to the nearest hundredth.

### Diagram Description:

The given image shows a right triangle with the following details:

- One leg of the right triangle, which is 10 feet long, is perpendicular to the base.
- The hypotenuse of the right triangle is 12 feet long.
- The angle opposite to the unknown length \( x \) is marked.

### Steps to Solve:

1. **Identify Known Values:**
   - Opposite side: 10 ft
   - Hypotenuse: 12 ft

2. **Apply the Sine Ratio:**
   - In a right triangle, the sine of an angle is given by the ratio of the length of the opposite side to the length of the hypotenuse.
   
   \[
   \sin(\theta) = \frac{\text{opposite}}{\text{hypotenuse}}
   \]
   
   Here, \(\theta\) is the angle \( x \).

3. **Calculate Angle \( x \):**
   
   \[
   \sin(\theta) = \frac{10}{12} = \frac{5}{6} \approx 0.83
   \]
   
   Using inverse sine function (\(\sin^{-1}\)), find the angle \( x \):
   
   \[
   \theta = \sin^{-1}(0.83)
   \]
   
   This will give the angle \( x \) in degrees. Use a scientific calculator to find the value.

### Result:

After calculating the value, round \( x \) to the nearest hundredth. Type your answer in the provided box.
