![### 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](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F89e7fbf9-0e55-4f4a-a0db-4898252833e3%2F190852ad-e9d2-41c2-a10d-ef89a0a99129%2Fzcvrzii_processed.png&w=3840&q=75)
