Hope this helps

Sorry if some of these are wrong

the ladder needs to be 7.43" from the building.

the ladder should be placed 18.68" up the building.

Explanation:

A right angle triangle is formed.

The distance from the base of the building to the window represents the opposite side of the right angle triangle.

The distance from the foot of the ladder, h to the base of the building represents the adjacent side of the right angle triangle.

The length of the ladder represents the hypotenuse of the triangle.

The 20" ladder needs to have a 5:2 ratio of distance to building and distance to window in order to be safe. It means that

Opposite side/adjacent side = 5/2

Opposite side/h = 5/2

Opposite side = 5h/2 = 2.5h

We would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side + adjacent side

Therefore,

20² = 2.5h² + h ²

400 = 6.25h² + h² = 7.25h²

h² = 400/7.25

h² = 55.17

h = √55.17

h = 7.43"

The distance from the top of the ladder to the base of the building is

2.5h = 7.43 × 2.5 = 18.58"
