Answer:
Step-by-step explanation:
Consider the diagram shown below.
Height of the observer, DE=1.5 m
Height of the chimney, BC=AC+1.5 m
Distance of the observer from the foot of the chimney, BE=28.5 m
Angle of elevation from the eyes of the observer to the top of the chimney =45
∘
AD=BE=28.5 m
Therefore,
tan45
∘
=
AD
AC
28.5
AC
=1
AC=28.5 m
Therefore,
Height of the chimney, AB=28.5+1.5=30 m
Hence, the height of the chimney is 30 m.
