  1. Please indicate subject, not grade level. That will help increase the chances that the appropriate teacher reads your question.

    Because of similar-triangle geometry rules, the ratio of shadow length to the height of the object casting the shadow is a constant. If the tree height is x,
    25/x = 9/6

    Solve for x.

  10. A tree casts a 25 foot shadow. At the same time of day, a 6 foot man standing near the tree casts a 9 foot shadow. What is the approximate height of the tree to the nearest foot?

    25/x = 9/6 (where 25 is the tree's shadow, x is the unknown height of the tree, 9 is the man's shadow and 6 is the man's height)

    solve for x
    cross multiply 25(6) = (9)x
    150 = 9x
    x = 150/9
    do the division
    x = 16.6
    the tree is 16.6 feet or about 17 feet tall
