I'm building a model of a German train station and I want to make a Jerkinhead roof ( clipped gable roof ) for it, but I feel like a jerk-in-the-head for not being able to figure out the math to make the measurements. Here is an example of the roof on a different N scale model:

The height of the triangular portion of the roof depends on how much of an angle that clipped roof comes in. It seems like there is a simple mathematical way of doing these roofs, but I'm a rookie to building models and have not found the answer ( heck, I don't even know where to look ).
Simply put, I want to know how to figure out how high to make that triangular portion based on how deep it is cutting into the main roof.
Any help would be appreciated!
