It depends on the way you look at it.

That's because you don't have much of a brain.
E is definitely larger than 90 degrees.

Maybe you said that because all you can say to people is "blah" your opinion doesn't matter.

It's a fact, not an opinion. Go back to English. Facts can be proven and the proof is almost every post you made in this thread.
On topic, I also came up with 4
and I'm not even in geometry O.o

12 degrees. maybe. let me spend time and check
HAHA BSing. My geometry intuition is really bad. don't listen to me.

Ok. The first step to begin to solve a geometry problem is NEVER state something jut because "it looks like it is more than 8 degrees"
If you draw AB and BE, then the triangle is split into three isoceles triangles (Because AB, AC, BE, and BF are radii).
Then assuming that ACB is x, then CBA is x, and therefore EAB is 2x. But, as trangle ABE is isoceles, BEA is also 2x. The last isoceles triangle is BEF, and as angle F is 78 degrees so is angle BEF.
We have then that angles ECF+CFE+FEC=180
So:
x+78+2x+78=180
and:
x=8=ECF

I just looked back at the silly way I did it, and it was wrong. I was trying to incorrectly find ABE using arcs, and at the same time I made a stupid subtraction mistake. Somehow I got the correct measure of ABE though. I don't know how I managed that. And I hadn't even looked at the answer yet. But I see how it's done now. That was a facepalm moment for me.
You mean isosceles

And... so...?
I meant the three angles of the single triangle in the drawing.
Oh, do you mean that was my mistake? No, that's correct.
The mistake I made was that I couldn't actually do it the way I was trying to, but I made two mistakes that somehow ended up getting the right answer. Those are still the measures of the angles in the triangle.

Okay I apologize for saying that you don't have much of a brain. No one deserves such an insult. But I just want you to know that you pissed me off when you claimed that my correct solution was wrong and continued to make a stupid statement about certain points being there to distract the rest of us, acting as if you were the only genius around here who didn't fall for that distraction and found the correct solution; as if the rest of us here trying to help you find your own mistake are intellectually inferior to you. And all this happened with the correct solution shown in your face.
Although I take back what I said about you not having much of a brain, I still quoted these posts to express my opinion that you refuse to use your brain to think logically.

Yea, they have they same radius.

That's what I did, so you get three isosceles triangles, and then you can get the values of the angles in terms of x. It didn't work for me before. That was where I was going before... was I foiled by an arithmetic error? I think so...

Only if you don't know what you're doing. This is clearly the case with you. Go back to school and leave the math to the people who can actually do it.
