Answer 1

Given

A ten-foot ladder is leaning against a building make a 65-degree angle with the ground

Answer

If the ladder is treated as hypotenuse and the height of the wall as perpendicular than

`\begin{gathered} \sin 65=(p)/(h) \\ 0.91=(p)/(10) \\ p=0.91*10 \\ p=9.1\text{ ft } \\ \end{gathered}`
