The distance in feet from the base of the wall to the bottom of the ladder is J. 4.0 ft.

Explanation:

Step 1:

According to the Pythagorean theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

The hypotenuse is the longest side of a right-angled triangle and is the side opposite to the right angle.

The hypotenuse measures 20 feet. The other two sides measure 19.6 feet and x feet.

Step 2:

Substituting the values we know, we get


20^(2) = 19.6^(2) + x^(2) .


x^(2) = 20^(2) - 19.6^(2).


x^(2) = 15.84, x = √(15.84).


x = 3.9799.

This value is closest to the value of 4.0 ft which is option J.
