Answer:
25.7 feets
Step-by-step explanation:
From the diagram attached, we could use trigonometry to obtain the height,h :
Using the trigonometric relation :
Sin θ = opposite / hypotenus
Opposite = h
Hypotenus = 26 feets
Sin 81° = h / 26
Height, h = 26 * sin 81°
h = 26 * 0.9876883
h = 25.679
Height, h = 25.7 feets
