Step-by-step explanation:
Hi there!
Let´s start writting the formula

If we multiplicate both sides by (x₂ - x₁):

Then if we add y₁ to both sides of the equation:

Then, the right answer is the answer c)

Answer:
The top of the ladder is 6.3 feet high from the ground.
Step-by-step explanation:
The given question can be expressed by the three sides of a right angled triangle. Let the height of the top of the ladder from the ground be represented by h.
Thus, applying the Pythagoras theorem to determine h, we have;
=
+ 
=
+ 
121 =
+ 81
= 121 - 81
= 40
h = 
= 6.325
h = 6.325 feet
The top of the ladder is 6.3 feet high from the ground.
