    Answer: 12cm

    Step-by-step explanation:

    They are similar, so we can set an equation of:

    the ratio of length and width of the big triangle equal to the ratio of length and width of the small(second) triangle.

    36:9 = x:3

    36/9 = x/3

    9x = 3(36)           by use the cross multiply

    9x = 108

    x = 12 cm
