## Step 1The problem describes a right triangle, where the ladder acts as the hypotenuse, the height at which the ladder touches the wall is the opposite side, and the distance from the foot of the ladder to the base of the wall is the adjacent side.## Step 2We are given that the height at which the ladder touches the wall is twice the distance from the foot of the ladder to the base of the wall. Let's denote the distance from the foot of the ladder to the base of the wall as
. Therefore, the height at which the ladder touches the wall is
.## Step 3We can apply the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. In this case, the hypotenuse is the ladder, which is 15 feet long.### **The Pythagorean theorem:
**## Step 4Substituting the given values into the Pythagorean theorem, we get:### **\(x^2 + (2x)^2 = 15^2\)**## Step 5Solving this equation will give us the value of
, which is the distance from the foot of the ladder to the base of the wall.
