B=72
ECD=72
CED=36
AED=144
Hope they are correct
ECD=72
CED=36
AED=144
Hope they are correct
passo:
write full explanation
in abce opp. wider are equal hence it's a parllelogram
sides*
hence a+b=180 b=72
ecd=108 hence ecd=72
wrong
how?

As the figure is a parallelogram,
∠a+∠b=180°
so,∠b=78°
∠ECD=78°(since ab ║ce)
∠CED=78°
∠AED=24°
∠a+∠b=180°
so,∠b=78°
∠ECD=78°(since ab ║ce)
∠CED=78°
∠AED=24°
