The image shows a trigonometric problem involving a right triangle. The lengths of the legs of the triangle are $6$ and $9$, and we are to find the length of the hypotenuse and the tangent of the angle $\theta$ opposite to the leg of length $6$.

Let's start by finding the hypotenuse $c$ using the Pythagorean theorem:

$c = \sqrt{6^2 + 9^2} = \sqrt{36 + 81} = \sqrt{117} = 3\sqrt{13}$

Next, we find $\tan(\theta)$:

$\tan(\theta) = \frac{\text{opposite}}{\text{adjacent}} = \frac{6}{9} = \frac{2}{3}$

To summarize:

1. The length of the hypotenuse $c$ is $3\sqrt{13}$.
2. The tangent of the angle $\theta$ is $\frac{2}{3}$.
