any 1

x = 105°

Let O the center of the circle.

COB = 90°
hence, CAB = 45°

DOA = 140°
hence, DBA = 70°

In the triangle EAB, angles are 45° , 70° and AEB, hence, AEB = 75°.

AEB + x is a flat angle :
x = 180° - 75°

Thank you!

And ooops, I made a mistake at the final :

AEB = 65° (of course) and x = 115°

Sorry for that...
