Answer:
The pitch (slope) of the roof is [tex]0.25[/tex] or [tex]25\%[/tex]
Step-by-step explanation:
we know that
The formula to calculate the slope is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
where
In this problem we have
[tex]{y2-y1}=2.5\ m[/tex] -----> is the vertical distance (rises)
[tex]{x2-x1}=10\ m[/tex] -----> is the horizontal distance (run)
substitute the values
[tex]m=\frac{2.5}{10}=0.25[/tex]
convert to percentage form
[tex]0.25*100=25\%[/tex]
