1 answer:
Answer:
Final answer is slope = 0.73
Step-by-step explanation:
Given that an old house has a basement stairway.
Stairway has steps with 7.25 inch vertical risers and 10 inch horizontal treads. Now we need to find about what is the slope of the stairway. Also round the answer to two decimal places.
Now round that value to two decimal places gives 0.73
Hence final answer is slope = 0.73

So basically the ladder is creating a right triangle with the ground and the wall. Ladder is the hypotenuse (h), building = b, ground = g
b = h - 22 ft
g = 1010 ft
use Pythagorean Theorem to determine the length of h:
The h^2 terms cancel out to = 0
b = h - 22 ft
g = 1010 ft
use Pythagorean Theorem to determine the length of h:
The h^2 terms cancel out to = 0
