Answer:

The height is 28.9 ft

Step-by-step explanation:

The given scenario can be shown in the figure below:

This forms a right-angle triangle.

Applying Pythagorean rule, we have:


30^2=8^2+h^2

Where h is how high above the ground the top of the ladder is touching the house.

Solving for h, we have:


\begin{gathered} h^2=30^2-8^2 \\ \\ h^2=836 \\ \\ h=\sqrt[]{836} \\ =28.9 \end{gathered}

The height is 28.9 ft
