Static truss

    Im having trouble understating this:

    The last part:

    DEz=8333N(5/15) where does this come from?

    15m is the hight and 5m is the base of the triangle.

    It's the horizontal component of DE i.e FDEcosθ
    where cosθ = Opposite/Adjacent = (15/5)

    but isn't cosine adjacent/Hypotenuse?
