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
[tex]\begin{gathered} \sin 65=\frac{p}{h} \\ 0.91=\frac{p}{10} \\ p=0.91\times10 \\ p=9.1\text{ ft } \\ \end{gathered}[/tex]
