length = 17.35

What is the angle of the top line, and the far left line...

The angle is 78.4 degree's and the other angle is opposite that:

90 - 78.4 = 11.6 + 90 = 101.6 degree's

a (squared) + b (squared) = c (squared)

Works with ALL RIGHT triangles...

So, you take the top line minus the bottom one. (gives you base of triangle length) Then you square that, and add it to 17 squared (side of said triangle) then get the square root of that number...

EDIT= how did you do that "cabinetry"???

I didn't use math if that's what your asking.

I simply drafted the side profile in sketch up and used the angle finder.

Complicated math ain't my strong suit.

hmm i should of thought of doing that.and i just did it to see and it does come out to 78.4
