1 answer:
Answer:
The length of the ladder is 13 feet
Step-by-step explanation:
Here, we are interested in calculating the length of the ladder.
To get this, we shall need a diagrammatic representation. In the diagram, we shall be having a right angled triangle. Please check the attachment for this.
Mathematically, the length of the ladder represents the hypotenuse of the right angled triangle while the height of the window and the distance of the ladder to the feet of the window represents the other two sides of the triangle.
To calculate the length of the ladder, we shall be using Pythagoras’ theorem.
Mathematically, it’s states that the square of the length of the hypotenuse is equal the sum of the squares of the two other sides.
let’s say the length of the ladder is l
Mathematically;
l^2 = 5^2 + 12^2
l^2 = 25 + 144
l^2 = 169
l = √169
l = 13 feet
