 I don't think you need trig, he gives you one angle, the one on the other side is obviously the same so you have enough to work out the other angles just subtracting them from 360. 

Apart from the fact you're using 2 triangles, is that not in fact trig?

In the top view, if you draw a line down from the 10.5deg angle you create a right angle at the baffle.  the angle to the right of this will be 79.5deg.

We know that the internal length of this line is 372 (438 - [18+18+30])

you can then plug these into something like this to get the rest of the dimensions/angles

Nah you honestly don't need to use any trig, the angle of the inside of the back of the box to the sides will be the same as the angle of the outside of the baffle to the sides.
