The pitch of a roof is its slope. The roof of a home rises vertically a distance of 8 ft through a horizontal distance of 15 ft.

PIT_PIT [208]

If we discuss this as if it is a triangle then the "rise" is the vertical side and the "run" is the adjacent side.
So the ratio of the rise to the run is 8 / 15 which equals 0.5333333333 
To find the angle of this roof pitch we look up the arc tangent of 0.5333333333 and we find that is 28.072 Degrees
