    Answer:

    10.72m

    Explanation:

    We have

    h'/h = -(q/p)

    h’ = height of the object’s reflection = 3.3cm

    h = height of the object = ????

    q = distance of object from mirror = 26m

    p = distance of reflection in mirror = 8.0cm

    h = (h')/(q/p)\\\\h= \frac{0 .033m}{ (0.08m/26m)} \\\\h = 10.72 m

    The tree has a height of 11m.

    you need to solve first for the distance of the image using the mirror equation.

    Then find the height using the magnification equation.
