Accepted Solution
A:
If BC is your shortest like, that would make it line A of the pythagorean theorem. AC is line B, and that would make line AB the hypotenuse, or line C. So.... a^2+b^2=c^2 12^2+18^2=c^2 12*12=144 18*18=324 324+144=c^2 468=c^2 Because it is squared, you can divide by 2 and get your answer to line AB.
