Answer:
39.9 ft
Step-by-step explanation:
We solve using the Trigonometric function of Tangent
The formula for angle of elevation =
tan θ = Opposite/Adjacent
θ = Angle of elevation = 35°
Adjacent = 57 feet
Height = Opposite = x
Hence,
tan 35 = x/57 ft
Cross Multiply
x = tan 35 × 57 ft
x = 39.911829678 ft
Approximately the height of the building = 39.9 ft
