Question

The ladder to the slide is 21 feet high. how long is the slide

Answer 1

To find the slide we can us the pythagorical theorem that say:

`h=\sqrt[]{l^2_1+l^2_2}`

Where l1 and l2 iare the leg of the triangle so in our problem will be:

`\begin{gathered} h=\sqrt[]{28^2+21^2} \\ h=\sqrt[]{784+441} \\ h=\sqrt[]{1225} \\ h=35 \end{gathered}`

So the slide is 35 ft
