Explanation:

From the statement we can make the following drawing of the situation:

We calculate the value of x by means of the Pythagorean theorem:

`\begin{gathered} h^2=a^2+b^2 \\ h=50 \\ a=40 \\ b=x \end{gathered}`

replacing and resolving:

`\begin{gathered} 50^2=40^2+x^2 \\ x^2=2500-1600 \\ x=\sqrt[]{900} \\ x=30 \end{gathered}`
