Answer :

Answer:

5

Step-by-step explanation:

Pythagorean Theorem. The 13-meter ladder is leaning against a wall, so it's the hypotenuse.

It reaches 12 meters up, so 12 is one leg.

[tex]a^{2} +b^{2}=c^{2}[/tex]

[tex]a^{2}+12^{2}=13^{2}[/tex]

[tex]a^{2}+144=169[/tex]

[tex]a^{2}=25[/tex]

a = 5
