Question

the letter to the top of the surface light is 20 centimeters in the slightest 45 meters long. how far is it from the bottom of the slide to the ladder?

Answer 1

we can use the pythagorean theorem

`\begin{gathered} c^2=a^2+b^2 \\ 45^2=27^2+b^2 \\ 2025=729+b^2 \\ 2025-729=729+b^2-729 \\ 1296=b^2 \\ b=\sqrt[]{1296} \\ b=36 \end{gathered}`

answer is 36 meters
