What is the measure of abc ?

Answer:
Option D 63°
Step-by-step explanation:
Two secants AE and CD intersect each other at point B inside the circle.
So by secants theorem,
[tex]\frac{m(AC)+m(DE)}{2}[/tex] = ∠ABC = ∠DBE
= [tex]\frac{1}{2}[/tex] ( 82 + 44 )
= [tex]\frac{1}{2}[/tex] ( 126)
= 63
Option D 63° is the answer.
