A contractor is checking the height of the frame for a building his company is constructing. He stands at some distance from the
tatiyna

Answer:

  about 102 feet

Step-by-step explanation:

From the definition of the cotangent function, we can write ...

  h·cot(α1) = d1

  h·cot(α2) = d2

Where h is the building height and (α1, d1), (α2, d2) are (elevation angle, distance from the building) for the two cases.

We have d2 - d1 = 10 ft, so ...

  h(cot(68°) -cot(73°)) = 10 ft

  h = (10 ft)/(cot(68°) -cot(73°)) ≈ (10 ft)/(0.404026 -0.305731) ≈ 101.73 ft

The building is about 102 feet tall.
