Answer:
i think 88
Step-by-step explanation:
(it's been a while since I've done this so I'm not too sure it's correct)
The formula we need to use is
2πr(angle/360)
we need the radius (r)
To get r we need angle AES
180-80= 100
using the equation from before
88=2πr*(100/360)
raidus: 50.42
Then to get the length CD we need angle DEC
180-80=100
2π*50.42*(100/360)=88
there probably was some kind of shortcut we could've used to figure this out faster but whatever
