Find the height of a building if the angle of elevation to the top of the building changes from ° to ° as an observer moves a distance of feet toward the building.
observer moves a distance of (from original point) feet toward the building, and rest of a distance to building is
observe triangle with legs and (height)
=>
total distance from the building is
then triangle with legs and
-> height of the building
then
ad total distance is
check angles:
°
°...which confirms solution
