Answer:
6
Step-by-step explanation:
The angle bisector divides the other segments proportionally. There are many ways the proportion can be written. One is ...
XN/NY = XA/AY
XN = NY×XA/AY = 4 × 18/12
XN = 6
see below
t> -3
There is an open circle at -3 since there is no equals sign
t is greater so the line goes to the right
