Consider triangles CXY and BXY. In these triangles,
- - proven
- given
- reflexive property
By SAS postulate, 
Congruent triangles have conruent corresponding parts. So,
It is the last one. A closed circle means less than or equal to, so that crosses out the top two. The third says five is greater and we know that is not true because the line is decreasing in value. It must be the fourth.
