NeTakaya

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 = $\dfrac{\textrm height of ladder up wall}{\textrm distance of base of ladder from wall}$

Or, x = $\dfrac{2 meters}{0.4 meters}$

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
