Painting Math
Cheferos needs to paint the high walls in his foyer, which rise 18'. Cheferos stands roughly 6'4" with workboots on, can (comfortably) reach another 1' higher than that for extended periods, and the maximum safe working height of a ladder is generally 3' shorter than its maximum length. Assuming Cheferos uses the safe ladder ratio of 1:4, meaning a ladder should stand 1 unit of distance out from the wall for ever 4 units of height it rises, what is the shortest safe ladder size Cheferos could rent? Hint: Use the Pythagorean Theorem.
