    Answer: the height of the tree is 27 feet

    Step-by-step explanation: We can set up a proportion comparing the height of each object to the length of the shadow.


    h
    s


    h
    15
    =
    18

           10


    Cross multiply

    10

    h
    =
    18

    15


    10
    h
    =
    270


    Use the multiplicative Inverse


    10

    h

    10

    =

    270

    10


    h
    =
    27
