    By definition, the pitch of a roof is its vertical rise divided (In this case is 7 feet) by its horizontal measurement, which is called "Run" (42 feet). Therefore, you can calculate the pitch of this roof (P) by applying the following steps:

    P=Tan^-1 (Rise/Run) Rise=7 feet

    Run=42 feet

    When you substitute these values into the formula P=Tan^-1 (Rise/Run), you obtain:

    P=Tan^-1 (Rise/Run)

    P=Tan^-1 (7/42) P=9.46º

    What is the pitch of the roof?

    The answer is: The pitch of the roof is 9.46º.
