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.

Ok, but that only gives the angles, and you will need the length of the sides if you want to do it without drawing it out.

You get your bit of wood, you draw out the cab on it and start cutting!  Doesn't matter if you end up drifting off the plans a bit!

I've managed for years with plans drawn on the back of envelopes.  Possibly in crayon.
