Answer:
≈ 9.9 feet
Explanation:
We can use the Pythagorean theorem to solve this problem. Let x be the distance from the house to the base of the ladder. Then:
x^2 + 15^2 = 18^2
Simplifying and solving for x, we get:
x = sqrt(18^2 - 15^2) = 9.9 feet (rounded to the nearest tenth)
Therefore, Jaquira should place the base of the ladder approximately 9.9 feet away from the house.
