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

3. liliy

rounded: 20

4. Tchan

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

5. liliy

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.

6. Tchan

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

7. liliy

oh, ya- sorry. it does work!

Thanks you for your help though
