Answer:

Given that A ladder, 100 m long reaches a point on the high-rise building that is 80 m  above the ground.

Given that ground is horizontal.

The ladder, building and ground forms a right angled triangle.

The figure is attached below

In the right angled triangle ABC,

AC represents the length of ladder

AC = 100 m

AB represents the height of building

AB = 80 m

BC represents the distance between the foot of building to foot of ladder

BC = ?

Pythagorean theorem, states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle :]

By above definition for right angled triangle ABC,

$=> \sf AC^2 = AB^2 + BC^2$

$=> \sf (100)^2 = (80)^2 + BC^2$

$=> \sf 10000= 6400 + BC^2$

$=> \sf BC^2 = 10000 - 6400$

$=> \sf BC^2 = 3600$

Taking square roots on both sides we get :]

$=> \sf BC = \sqrt{3600 }$

$=> \textsf{ \textbf{ BC= 60 meters}}$

Thus the distance between the foot of building to foot of ladder is 60 meters.
