Answer:

  37.3 ft

Step-by-step explanation:

SOH CAH TOA reminds you that ...

  Tan = Opposite/Adjacent

In this geometry, the side adjacent to the angle is the 80 ft shadow, and the opposite side is the height of the building. Then we have ...

  tan(25°) = height/(80 ft)

  (80 ft)·tan(25°) = height ≈ 37.3 ft
