Answer:
1063 ft
Step-by-step explanation:
For shadow problems, we assume the sun's rays are parallel, so the triangles formed are similar. That means the ratio of height to shadow length is the same for each object.
h/(580 ft) = (5.5 ft)/(3 ft)
h = (5.5 ft)(580/3) ≈ 1063 ft
The height of the monument is about 1063 feet.
