Answer:
7.65 meters
Step-by-step explanation:
We have to:
Tree = AB = 13 m.
Person = A'B '= 170 cm = 1.7 m
AC =?
A'C '= 1 m
Thales' Theorem applies. Similar triangles: are those that have a similar shape but on a smaller or larger scale and their angles are the same.
AB / A'B '= AC / A'C'
13m / 1.7m = AC / 1m
Clear h1
AC = 13 * 1 / 1.7
AC = 7.65 m
The height of the tree is 7.65 meters
