Quizplus · Accepted Answer

Pitch is defined as the vertical rise per unit of horizontal run. So, we can calculate the pitch of the roof by dividing the rise by the run.

Pitch = Rise/Run = 5/9

Therefore, the pitch of the roof is 5/9 or Choice C).

If the Rise of the Roof Shown in the Illustration −59- \frac { 5 } { 9 }−95​

If the Rise of the Roof Shown in the Illustration $- \frac { 5 } { 9 }$
