A vertical wall 1.6 m high is on horizontal ground.

A ladder of length 2.5 m rests against the wall.

The ladder rests on the ground 0.7 m from the wall.

Work out the length of the ladder that extends above the wall.

Answer 1

Answer: 1.75 meters

Step-by-step explanation:

Hi, to answer this question we have to apply the Pythagorean theorem.

c2 = a2 +a2

Where c is the hypotenuse ( the longest side ) and a and b are the other two sides of the right triangle.

In this case, the ladder is the hypotenuse.(c)

Replacing with the values given:

c2 = 0.7^2 +1.6^

Solving for c:

c2 = 0.49+2.56

c2 = 3.05

c = √3.05

c = 1.75 m
