### Finding Trigonometric Ratios

**Problem:**

Find the sine, cosine, and tangent of angle \( A \) pictured below. Enter exact expressions or round your answers to the nearest thousandth.

**Diagram Description:**
The diagram shows a right-angled triangle with one of the non-right angles labeled as \( A \). The side opposite to angle \( A \) is not labeled, the adjacent side is labeled 5, and the hypotenuse is labeled 6.

**Formulas to Use:**
- Sine: \(\sin A = \frac{\text{opposite}}{\text{hypotenuse}}\)
- Cosine: \(\cos A = \frac{\text{adjacent}}{\text{hypotenuse}}\)
- Tangent: \(\tan A = \frac{\text{opposite}}{\text{adjacent}}\)

**Calculation Steps:**
1. Identify the length of the opposite side using the Pythagorean theorem:
   \[
   \text{opposite} = \sqrt{\text{hypotenuse}^2 - \text{adjacent}^2} = \sqrt{6^2 - 5^2} = \sqrt{36 - 25} = \sqrt{11}
   \]
2. With the lengths of all sides determined:
   - Opposite side = \(\sqrt{11}\)
   - Adjacent side = 5
   - Hypotenuse = 6

3. Compute the trigonometric ratios:
   - \(\sin A = \frac{\sqrt{11}}{6}\)
   - \(\cos A = \frac{5}{6}\)
   - \(\tan A = \frac{\sqrt{11}}{5}\)

Below are the boxes provided to enter the values you calculated:

- **Sine of A:**
  \[
  \sin A = \boxed{\frac{\sqrt{11}}{6}}
  \]

- **Cosine of A:**
  \[
  \cos A = \boxed{\frac{5}{6}}
  \]

- **Tangent of A:**
  \[
  \tan A = \boxed{\frac{\sqrt{11}}{5}}
  \]

To compute rounded values to the nearest thousandth:
 
- \(\sin A \approx 0.558\)
- \(\cos A \approx
