    For the 1st problem:

    x = 10

    Because 3/5 = 6/x

    Simplify that and you get x = 10

    I'll work on the rest. Geometry isnt my strongest point

    In 1 we have similiar triangles.
    (x + 6)/6 = (5 + 3)/3
    3(x + 6) = 6(8)
    3x + 18 = 48
    3x = 30
    x = 10

    For problem 2, we can set up a ratio between the outer sides of the two trapezoids:

    10/5 = 14/x
    2x = 14
    x = 7
