painter has a 24-foot ladder that he is using to paint a house. For safety reasons, the ladder must be placed at least 8 feet fr
om the base of the side of the house. To the nearest tenth of a foot, how high can the ladder safely reach?
1 answer:
Answer:
this is a pythagorean theorem problem. 24 is the whole ladder, and if you draw it out, is a hypotenuse. 8 is a leg. . so 8^2 + b^2 = 24^2
b^2 = 512, so b = sqrt(512) = 22.6
