I've spent one hour looking at part d) and I still can't figure it out!!
Could someone explain what I'm missing here?

Well, if you look at the second theta angle, i think it's easier to look there.
It's a triangle, use your triangle knowledge to fill in the angles, you also know the side opposite said theta, (it's 2m)
Then you can use the Sine rule to find the side attached to the H on rectangle D.

you have found Θ....
one of the triangles with Θ has opposite = 2 and adjacent = 4 - h.....
