You can put this solution on YOUR website!
The unknown side length, x.

Use Triangle Inequality Theorem.
system%289%2B20%3Ex%2C9%2Bx%3E20%2C20%2Bx%3E9%29;
Solve for the possible solutions of x within this system. The result will be an inequality, NOT a specific value.


The last inequality of the system will give nonsense.
The other two inequalities of the system will give you highlight%2811%3Cx%3C29%29.
