Answer:
Because the building is 20m high, observer is 20 m from building as angle of elevation is 45°
Step-by-step explanation:
Now tan 60°=1.732
=(total height of tower and building)/dist of observer from building
=(total height)/20
so total height=20*1.732
=34.64 m
and height of tower
=34.64-20
=14.64 m ANSWER
