Answer:
D
Step-by-step explanation:
The secant- secant angle ACE is one half the difference of the measures of the intercepted arcs, that is
[tex]\frac{1}{2}[/tex] (AE - BD ) = ∠ ACE , that is
[tex]\frac{1}{2}[/tex] (AE - 30)° = 40° ( multiply both sides by 2 )
AE - 30 = 80 ( add 30 to both sides )
AE = 110° → D
