Answer:
8020 feet
Step-by-step explanation:
The tangent relation can be used to answer this question, since it relates the sides of a right triangle to the acute angle.
tan(elevation angle) = (1472 ft)/(distance between)
Then ...
distance between = (1472 ft)/tan(10.4°) ≈ 8020 ft
The skyscrapers are 8020 feet apart.
