Question 711269: Hi, I had a math test today and we were allowed to go back and finish up since our class period was shortened. There was one problem I did not understand and it went something like this:
Find the like of the third side of the obtuse triangle with the longest side 36 and one of the legs 4.
(Those numbers were just made up)
I know that c^2 > a^2 + b^2 then the triangle is obtuse. But I also know that to find the range of the third side you would need to do: a + b = d and a - b = e, leaving you with e < x < d (Let x be any number within the given range). I just don't know how to find the range for the obtuse triangle. Thank you so much!

--------------
Do you mean length?
It has to be less than the sum of 36 & 4, < 40
----
To be obtuse, s^2 > 36^2 + 4^2
--> s > sqrt(1312)
-----------------------------
sqrt(1312) < s < 40
