Answer:
Height of tree = 100 m
Step-by-step explanation:
From the figure we can see a two similar triangles.
Points to remember
The ratio of of corresponding sides of similar triangles are equal.
To find the height of tree
Let 'h' be the height of tree, then we can write,
Height of girl = 150 cm = 1.5 m
3/(3 + 17) = 1.5/h
3/20 = 1.5/h
h = (1.5 * 20)/3
= 10 m
Therefore the height of tree = 10 m
