    1. You are dealing with two right triangles whose acute angle have the value \theta and whose hypotenuses are \overline{AD} and \overline{AB}(see attachment)

    2. According to the sketch:

    x = 1.5 \cdot \cos(\theta)

    y = 3.5 \cdot \sin(\theta)

    and: x+y=2.5

    3. Plug in the terms of x and y into the last equation and afterwards multiply through by 2.
