The diagram shows a 20-foot ladder leaning against a brick wall.
Wall
Which measurement is closest to x, the distance in
feet from the base of the wall to the bottom of the
ladder?
F. 0.4 ft
G. 0 9 ft
H. 2.0 ft
J. 4.0 ft

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

Step-by-step 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

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

45.3592

step-by-step explanation:

47 - 90 = 43

43 - 180 = x

x = 137
