![A right triangle has side lengths 5, 12, and 13 as shown below. Use these lengths to find cos A, tan A, and sin A.
The diagram shows a right triangle with:
- Hypotenuse \( AB = 13 \)
- Opposite side \( AC = 12 \)
- Adjacent side \( BC = 5 \)
Based on the right triangle:
- \( \cos A = \frac{\text{adjacent}}{\text{hypotenuse}} = \frac{5}{13} \)
- \( \tan A = \frac{\text{opposite}}{\text{adjacent}} = \frac{12}{5} \)
- \( \sin A = \frac{\text{opposite}}{\text{hypotenuse}} = \frac{12}{13} \)
