Respuesta :
a 13 ft ladder must reach 12 ft up the side of a house. how many feet from the house should the bottom of the ladder be placed?
Answer: 1 foot
Answer:
5 ft
Step-by-step explanation:
Ladder top, the wall and the horizontal distance will form a right triangle with:
- Hypotenuse = 13 ft
- Vertical leg = 12 ft
- Horizontal leg = x
As per Pythagorean theorem:
- x² + 12² = 13²
- x² = 169 - 144
- x² = 25
- x =√25
- x = 5 ft
