Question

The base of a ladder should be placed 2 feet from the wall for every 5 feet of ladder length. How can a 15-foot ladder safely reach? Round to the nearest hundreth.

Answer 1

Because you get 2 feet from wall per 5 feet of ladder,

15 * (2/5) = 3 * 2 = 6 feet from the wall.

Assuming you're looking for how high, x^2 + 36 = 225

x = 16.15 feet

Answer 2

Answer 3

Oops! My bad, the answer is just \[\sqrt{189}\] which is around 13.75 (:
