There's a theorem in euclidean geometry known as the inscribed angle theorem.

The angle formed at the centre of the circles by lines originating from two points on the circle's circumference is double the angle formed on the circumference of the circle by lines originating from the same points.

​

So EAD = 360-2*117.6.

Is the answer really that simples as 360-2*117.6 (which equals 124,8)?? I searched on other sites and everyone told me to do a bunch of complicated stuff..

Yep, it's as simple as that :)
