$\frac{a^2-ax+bx-ab}{a^2+ax-bx-ab} \cdot \frac{a^2+ax+ab+bx}{a^2-ax-ab+bx} = \frac{1}{a(a+x)-b(x+a)} \cdot (a(a+x)+b(a+x)) = \frac{1}{a-b} \cdot (a+b) = \frac{a+b}{a-b}.$

The length of a shadow of a building is 26 m. The distance from the top of the building to the tip of the shadow is 36 m, Find t

Korvikt [17]

Applying the Pythagorean theorem, the height of the building is: 24.9 m.

<h3>How to Apply the Pythagorean Theorem?</h3>

Where c is the length of the hypothenuse of a right triangle, and a and b are the legs of the right triangle, the Pythagorean theorem states that:

c = √(a² + b²).

The diagram of the building and its shadow form a right triangle as shown in the image below, where:

a = height of the building

b = 26

c = 36

Applying the Pythagorean theorem, we will have:

a = √(36² - 26²)

a = 24.9 m
