Answer:
distance between the base of the ladder from the bottom of the building = 5.18ft
Height of the building = 19.32ft
Step-by-step explanation:
The distance between the base of the ladder from the bottom of the building and the height of the building is given by
d = Lcosx
h = Lsinx
Where L is the length of the ladder, d is the distance between the base of the ladder and the bottom of the building, h is the height of the building and x is the angle between the ladder and the ground.
Given; x= 75° L = 20ft
d = 20cos75 = 5.18ft
h = 20sin75 = 19.32ft
If we are going to write the equation in its mathematical form, we will see that it becomes,
<span> f(x) = 17/(x – 5)</span>
The domain of the function is the number of x that would allow us to solve the equation and get a real value for f(x). In this equation, x can take any real numbers so long as it is not 5. This is because 5 – 5 in the denominator will lead to 0 which in turn makes the equation indefinite.
