Answer:
The slope of ladder is not within the safe range .
Step-by-step explanation:
Given as :
The height of the ladder up a wall = h = 2 meters
The distance of base of ladder from the wall = x = 0.4 meters
The estimated safety range of slope of ladder is between 6.3 and 9.5
Let The slope of the ladder = x
<u>According to question</u>
slope of the ladder = 
Or, x = 
Or, x = 5
So, The slope of the ladder = x = 5
Since The estimated range of slope between 6.3 and 9.5
And The calculate slope of ladder = 5
Hence, The slope of ladder is not within the safe range . Answer
