Answer:

12.7

Step-by-step explanation:

Use the Pythagorean Theorem.

The wall and ground are the legs. The ladder is the hypotenuse.

a² + b² = c²

8² + b² = 15²

b² = 225 - 64

b² = 161

b = √161 = 12.7

Answer: 12.7 ft

Answer:

12.7

Step-by-step explanation:

Its a pythagerous question question

so if the ladder is 8 feet from the wall the base is 8

and the ladder is 15 foot and is the hypotemuse

so 15^2-8^2=161^2

The root of 161 = 12.69 rounded to 2 dp

so 12.7
