Answer 4

You don't have a theorem for that? Interior Angles - Average of Subtended Arcs. Yoou have AC abd DB. That's ll you need.

Answer 5

i dont know how to solve it though :/

Answer 6

There's a theorem, but I don't know what it's call
But if you were to apply it to your problem,
You would have

<AEC= 1/2 (arcDB + arcAC)

So now all you have to do is substitute the values of the arc to solve for the angle
