Question

To estimate the height of a building, two students find the angle of elevation from a point (at ground level) down the street from the building to the top of the building is 39 degrees

From a point that is 350 feet closer to the building, the angle of elevation (at ground level) to the top of the building is 53 degrees. If we assume that the street is level, use this information to estimate the height of the building.

Answer 1

The complete solution is provided in the attachments.

53° 390 D r seg 350 feet AB= height of the building = h. D is the point where students au located C is a point that is 350 feet closer to the building from point D.

sh. [ Cot (39") - Cot (530) = 350 ah [1.235 – 0.759] = 350 3 0.481 h = 350 a h= 3.500 ah= 727.65 The height of the building is 727.65 feet
