Snooker is a kind of pool or billiards played on a 6-foot-by-12-foot table. the side pockets are halfway down the rails (longside) |------| | |12 | | | | |------| 6 Find the distance, to the nearest tenth of an inch, diagonally across from the corner pocket to side pocket

you know the "long side" is 12 ft long so half way must be 6ft long or 72 inches. the "short side" is 6ft long also so it is 72 inches as well. so using a^2 + b^2 = c^2 you can solve for the missing side "c" in inches. so 72^2 + 72^2 = C^2 or the square root of 10368 inches.
\[\sqrt{2*6^2}=6 \sqrt{2}= 8.49 \text{ ft} = 101.88 \text{ inches} \]
i don't think he knows the properties of a 45, 45, 90 triangle yet... :/
