    Tried using systems of equations to try to solve it at one point

    i think you should use ratios and proportions... \(\large \frac{2}{10}=\frac{3}{x} \) find x... i'm not sure but this is an educated guess. if i figure out any definite sure answer, i'll let you know

    is there any given relation between AB and CD?

    is that picture drawn exactly as your problem shows it?

    if the picture is the exact question then xy is smaller than uv

    well according to what i see in the diagram, the ratios should suffice for the solution

    xy is obviously longer than uv in the picture, in your diagram, it looked different so it got me thinking but in your picture, i think the ratios will solve it :) so find x and tell me what u get
