An engineer on the ground is looking at the top of a building. The angle of elevation to the top of the building is 22°. The eng
ineer knows the building is 450 ft tall. What is the distance from the engineer to the base of the building to the nearest whole foot?
1 answer:
Let the distance from the engineer to the base of the building be x, then
tan 22 = 450/x
x = 450/tan 22 = 1,113.79
Therefore the distance from the engineer to the base of the building to the nearest foot = 1,114 feet
