Question
You place a 24-foot ladder 10 feet away from the house. The top of the ladder just reaches a window on the second floor. How high off the ground is the window?
Hint:
Pythagoras' theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle 90°.
If a is the perpendicular, b is the base, and c is the hypotenuse, then according to the definition, the Pythagoras Theorem formula is given as
c2= a2 + b2
The correct answer is: the height of the window above the ground is 21.8 ft
Here, Length of base(b) = 10 ft
length of hypotenuse(d) = length of ladder = 24 ft
Let’s say that the height of the window on the second floor is a
Using Pythagoras theorem
d2 = a2 + b2
242 = a2 + 102
a2 = 576 - 100
a = 
m 
21.8 ft
Final Answer:
Hence, the height of the window above the ground is 21.8 ft
m 21.8 ftFinal Answer:
Hence, the height of the window above the ground is 21.8 ft
