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
