A ladder is leaning against the side of a building. The
cupoosta [38]

Answer:

16 ft

Step-by-step explanation:

Based on the situation above, it forms into a right triangle. Therefore we can apply the Pythagorean Theorem. We will use the formula below:

c = √( a² + b²)

In the problem above, the ladder acts as the hypotenuse denoted by c. It has a length of 20 ft. While the base denoted by b is 12 ft. Therefore, we need to solve for a. We will derive the formula above.

c² = a² + b²

a² = c² - b²

a = √( c² - b² )

a = √( 20² - 12² )

a = 16

The unit is in ft.

Correct me if I'm wrong. I hope it helps.
