Answer:
The value is [tex]m = 0.9022[/tex]
Step-by-step explanation:
From the question we are told that
The length of the treads is [tex]a = 9 \ inch[/tex]
The length of the risers is [tex]b = 8.12 \ inch[/tex]
Generally the slope of the staircase is
[tex]m = \frac{b}{a}[/tex]
=> [tex]m = \frac{8.12}{9}[/tex]
=> [tex]m = 0.9022[/tex]
