Math Help Please Lots of points

Answer 1

• G F is a perpendicular bisector

So

• A F=AB/2=86/2=43

Med ians of any tria ngle bise cts each other at 2:1 ra t io at cen troid.

So

• A G=C G=100

Apply Pythagorean theorem

`\\ \tt\hookrightarrow EC^2=CG^2-EG^2=100^2-60^2=10000-3600=6400\implies EC=80`

Now

• BE=EC=80
