Ответ:
12 yards
Step-by-step explanation:
From. The picture attached, we could obtain the angle of elevation, θ from the curb of the street to the top of the building.
Using trigonometric relation :
Tanθ = opposite / Adjacent
Opposite = 30 yards
Adjacent = 40 yards
Tanθ = 30/40
θ = tan^-1(0.75)
θ = 36.869897°
Distance between curb of street and flagpole :
(40 - 24) yards = 16 yards
Let height of flagpole = h
Tanθ = opposite / Adjacent
Opposite = h yards
Adjacent = 16 yards
Tan36.869897 = h/16
0.75 = h / 16
h = 0.75 * 16
h = 12 yards
