Answer:
√63 or 7.94
Step-by-step explanation:
To solve this, I used the Pythagorean Theorem which states "a² + b² = c²".
The ladder's length - 12 - would be the hypotenuse; c. The ladder is 9 feet away from the wall. To find how high the ladder rests on the wall:
c² - b² = a²
12² - 9² = c²
144 - 81 = 63
√63 = 7.9372539331937717715048472609178
We can round this to 7.94 But the answer will most likely be √63.
