Answer:
x=10
Step-by-step explanation:
Start by finding angle AED:
Opposite angles in a cyclic quadrilateral add up to 180
so 180-110=70 (angle AED) (=AEC because on a straight line)
Angle AED must be equal to angle EAD because they have equal side lengths.
Find angle ADE by 180-(70+70)=40
Find angle AEB:
- find DAB 180-(110+40)=30
DAB+EAD=EAB=EAC
(EAB=EAC since A and B are points on the same straight line)
30+70=100
Then look at triangle AEC
180-(EAB+AED)=x
180-(100+70)=10=x
