A painter leans a 12 ft ladder against a building. The base of the ladder is 5 ft from the building. To the nearest foot, how high on the building does the ladder reach?

Respuesta :

Answer:

3 ft

Step-by-step explanation:

Ladder = 12 ft

Distance between base of the ladder and the building = 5 ft

a² + b² = c²

a² + 5² = 12²

a² = 12² - 5²

a² = 144 - 25

a² = 119

a = √119

a = 3.3 ft

a = 3 ft (nearest ft)
