A 12-ft ladder leans against a large house. If the base of the ladder is 5 ft from the base of the house, whatis the angle formed by the ladder and the house? What is the angle formed by the ladder and the ground?

Respuesta :

From the problem, we construct the diagram as follows:

Using trigonometric functions, we have:

[tex]\begin{gathered} \sin x=\frac{5}{12}\Rightarrow x=\sin⁻¹(\frac{5}{12}) \\ \\ \cos y=\frac{5}{12}\Rightarrow y=\cos⁻¹(\frac{5}{12}) \end{gathered}[/tex]

Finally, we conclude that:

The angle formed by the ladder and the house: x = 24.624°

The angle formed by the ladder and the ground: y = 65.376°
