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
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
