An engineer on the ground is looking at the top of a building.
The angle of elevation to the top of a building is 38°.
The engineer knows the building is 300 ft tall.
What is the distance from the engineer to the base of the building to the nearest whole foot?
:
let d = dist to the building
Use the tangent of the angle of 38, where side op = 300; side adjacent = d
tan(38) = 300%2Fd
.7813 = 300%2Fd
mult by both sides by d
.7813d = 300
d = 300%2F.7813
d = 384 ft
