1. Medians $\overline{AX}$ and $\overline{BY}$ of $\triangle ABC$ intersect perpendicularly at point $O$. We know the lengths $AX = 12$ and $BC = 4\sqrt {13}$. Find the length of the third median, $CZ$. (Is not: 200 or 4sqrt22)
2. As shown in the diagram, $\overline {AD}, \overline {BE},$ and $\overline {CF}$ are concurrent. We know that $CD=CE=BF=4$ and $BD=AF=6$. What is $AE?
$ (Is not: 16/9)
+2862 So much easier to read with this post:

it has blessed and healed my eyeballs from un-rendered LaTeX.
What I see on MY screen:
much better compared to what you see on YOUR screen, right?
+19 Thank you for blessing my eyes with this holy water. 🙏 Anyway, this guest is really rich-- there are a lot of dollar signs lol
+2862 Also, for number 1. This is how far I got.
Using the properties of a median through a centroid, I found OB through pythagorean theorem
I also found AO through median properties
Notice that AOB is a right angle through supplements.
I you used pythagorean theorem to find AB?
Notice triangles AOB and ZOB are similar.
Since it is a median, we know that the triangles ZOB and AOB are in a ratio of 1:2, respectively. I also know the area of AOB because base and height are known.
So, how would I find OZ?
+2862 For number 2.
You have to use similar triangles.
Sorry I ran out of time gotta go 
also, why is "help me please" in the top of Sticky Topics?
