A ladder 50 dm long when set against the wall of a house just reaches a window at a height of 48 dm. How far is the lower end of
1 answer:
Answer:
14dm
Step-by-step explanation:
To solve this question we can use the Pythogorean theorem
a^2 + b^2 = c^2
In this case, The ladder is the hypotenuse, the height is one of the leg of the right angle triangle
Let's keep the missing side as x
If we apply the theorem,
x^2 + 48^2 = 50^2
x^2 + 2304 = 2500
x^2 = 2500 - 2304
x^2 = 196
