Incline degree?

Does anyone know what the exact degree of a standard Trackmaster sloped rail piece is?

Amateur math time???

Length 17" - 3" rise = 10 degrees??? ...maybe? maybe not?, its been a long time since shop math.

Ha ha...if I knew how to get the answer I wouldn't have asked! ...nor do I have a protractor, nor am I going to go buy one just to take a single measurement, nor would I know how to go about using a protractor to make the calculation. :/
Thanks though!;D

Rise is 3"
Run is 17"
