What's your point Manus?
Those are all "givens".
Like it is given that angleADB = 70;
so automatically ODE+CDE = 180 - 70 = 110.

I used the facts that the sum of the angles in a triangle is 180 degrees as is a straight line.
A negative angle doesn't make sense but -5 and 55 are the only solutions of the equations in my previous post.

Yes but in the post before I gave the answer: -5 and 55.

OED = -5
ODE = CDE = 55
CED = 105
Just fill it in.. it is correct.

Angle OED + Angle ODE = 50
Angle CED + Angle CDE = 160
Angle OED + Angle CED = 100
Angle ODE + Angle CDE = 110

OED = 54
ODE = -4
CED = 46
CDE = 114

Just fill it in ... it is correct.
Thanks from Denis

There are infinitely many solutions of the four equations; the equations aren't independent.
