So we first need to find A because we need to find arc BC
Line segment BE is a diameter, so it equals 180 degrees
Subtract arc CE from arc BCDE
CD+DE=65
180-65=115
We now know that arc BC=115 degrees
Now, we need to add up all the arc measures inside or arc FBE
FB+BC+CD+DE
45+115+40+25=225
The measure or arc FBE=225 degrees
hope this helps:))
