Answer:
[tex]\large\boxed{x=15.983\ m\approx16\ m}[/tex]
Step-by-step explanation:
Use tangent:
[tex]tangent=\dfrac{opposite}{adjacent}[/tex]
We have:
[tex]opposite=x\\adjacent=22\ m\\\alpha=36^o[/tex]
[tex]\tan36^o\approx0.7265[/tex]
Substitute:
[tex]\dfrac{x}{22}=0.7265[/tex]
[tex]\dfrac{x}{22}=\dfrac{7265}{10000}[/tex] cross multiply
[tex]10000x=159830[/tex] divide both sides by 10000
[tex]x=15.983[/tex]
