The roof of a factory rises vertically 7 ft through a horizontal run of 42 ft. What is the pitch of the roof?
Accepted Solution
A:
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:
