Most staircases in use today have 9−inch treads and 8 12 −inch risers. What is the slope of a staircase with these measurements?

Sati [7]

Answer:

The value is $m = 0.9022$

Step-by-step explanation:

From the question we are told that

The length of the treads is $a = 9 \ inch$

The length of the risers is $b = 8.12 \ inch$

Generally the slope of the staircase is

$m = \frac{b}{a}$

=> $m = \frac{8.12}{9}$

=> $m = 0.9022$
