    then do Pythagorean theorm. 18^2+b^2=27^2.

    so would \[\sqrt{27^{2}-18^{2}}\] work?

    no, well, think about it the square root would cancel the squares so you would be left with 27-18. and that gives you 9.

    no you square the numbers then subtract then and then find the square root of that number wich is 20
