Z odleglosci 30 m od wiezowca widac jego dach pod katem 60 stopni.Oblicz wysokosc tego budynku.
odlegosc od bubynku =30m
wysoksoc budynku=h
kat ostry α=60°
tg60°=30/h
√3=30/h
h=30/√3=(30√3)/3=10√3=10·1,73=17,3 m
odp: Budynek ma wysokosc 17,3m
d = 30 m
alfa(a) = 60*
H = ?
d/H = tg(a) I*H
H *tg(a) = d /:tg(a)
H = d/tg(a)
tg60* = V3
H = 30m/V3 *V3/V3 = 30V3/3 m
H = 10V3 m
H = 17,32 m
==========
