Estimate the hypotenuse of the triangle

[suspenc3]

Hi I just had a question on a quiz that asked to estimate the hypotenuse of triangle with given sides and a maximum error possibility. The two given sides were 5 and 12..i don't need an exact solution..but I was just wondering how to do it.

I Found the maximum Error that was possible and the said the the hypotenuse was 13+/-Error. Is this how to do it?

The max error was found using differentials.

Assuming that you did in fact find "Error", then yes, the hypotenuse would be 13\pm "Error". The point of the problem is, of course, to find "Error".

Yeah that's what I thought..But I didnt know if you were allowed to simply say the hypotenuse was 13..since finding that has nothing to do with differentials...I wasnt sure if there was actually a way to find the actual estimated length of it...without having to subtract the errror.
