A point G is 40m away from a building, which is 15m high. What is the angle of elevation to the top of the building from G?

stepladder [879]

Ф is the angle of elevation to the topo of the building from G.
length of leg adyacent to angle Ф=40m
length of leg opposite to angle Ф=15 m
tan Ф=leg opposite / leg adyacent=15/40=0.375
Ф=arctan 0.375=20.56º

The angle of elevation to the top of the building from G is 20.56º.
