Answer:
The height of the tree is 60 ft.
Step-by-step explanation:
From the given figure it is noticed that the height of the building is 120 ft.
In triangle ABC the points D and E are midpoints of AB and AC.
According to the midpoint theorem the line connecting the midpoints of two sides is parallel to third sides of the triangle. The height of he line segment is half of the third side.
The tree is connecting the midpoints of AB and AC. By midpoint theorem we can say that the height of tree is half of the height of building.
Height of building is
[tex]h=\frac{120}{2}[/tex]
[tex]h=60[/tex]
Therefore the height of the tree is 60 ft.
