height. The boy and he buildings are in a
straight line. The boy sees the top of those
buildings at an elevation
of 45 degree and 30 degree.
The nearest building is 20 m
away from him.
a) Draw rough figure
b Find the height of the buildings & distance between the buildings
​

Answer 1

Answer:

Assume a building be h. In Δ ABC, ACb = 30^0 tan30^0 = AB/BC = h/48 = h/48 1/√(3) = h/48 h = 48√(3)/3 = 16√(2) m Then, height of building is 16√(2) ...
