A maple tree casts a shadow of 45 ft long. At the same time, a 40-ft-long oak tree casts a shadow which is 60 ft long. Explain how you can use similar triangles to find the height of the tree. Then find the height of the tree.

  • Math -

    Draw similar right triangles, one with sides of 40 and 60, and the other with sides of h and 45

    Since the triangles are similar, the ratio of corresponding sides is constant.

    h/40 = 45/60
    h = 30

  • Math -

    30/50
