Question 198133
<font face="Garamond" size="+2">


That depends.  You don't make clear whether the missing side is the hypotenuse or one of the legs.  So it is either:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x = \sqrt{9^2+11^2}] if *[tex \LARGE x] represents the hypotenuse, or


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x = \sqrt{11^2 - 9^2}] if *[tex \LARGE x] represents one of the legs.


The arithmetic and rounding are yours to perform.
