    geometry triangle find x

    so we see a right triangle. it is divided into two parts, one is "x" and the other part that adds with "x" must be "5-x," correct?

    so how do we find what "x" is?

    POSSIBLE SOLUTION ?:

    1. set the equation to 3/x = 4/5-x
    2. cross multiply
    3. get 7x=15
    4. divide 7 on each side
    5. x = 15/7


    is this correct?

    your work is fine, In presenting a solution you should state how you constructed part 1 (by similar triangles).
