To find the angle formed where the ladder rests on the wall, we can use the tangent function. The slope is given as 8/3, which represents the ratio of the height of the wall (opposite side) to the base (adjacent side) of the triangle formed by the ladder against the wall.

The angle \( \theta \) can be calculated using the inverse tangent (arctan) function:

\[
\theta = \tan^{-1}\left(\frac{8}{3}\right)
\]

Now, we can compute this:

\[
\theta \approx \tan^{-1}\left(2.6667\right)
\]

Using a calculator:

\[
\theta \approx 69.4 \text{ degrees}
\]

So, the angle formed where the ladder rests on the wall is approximately **69.4 degrees**.
