-12 + (-11) > 5 + (-29)
-12 - 11 > 5 - 29
-23 > - 24 (true)
The issue with using the side-splitter to solve for x is that the side-splitter theorem is used to find lengths of the sides being split by parallel lines. In this case, the x is on a line that is parallel and thus could not be solved for using this theorem.
If we created a triangle where the tops of the non-parallel lines connected, we would be able to compare the following and solve:

However, none of this would help us solve for x using this theorem.
Because many of the chemical reaction that sustain life
