    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
