kari74 [83]

Answer:

AB= 8

XY= 5

BX= 4

XZ= 3.5

I believe these are the correct answers.

Step-by-step explanation:

If you look closely at the lines on each of the three outer triangles, it appears that all three of the triangles are the same measurements. So if you just pay attention to which lengths are for each different line, you can plug in the values for the ones you are missing. Hope this helps ❤
