Question

Can you help me with finding arc measure in circles?

Answer 1

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

$\frac{1}{2}$ (AE - BD ) = ∠ ACE , that is

$\frac{1}{2}$ (AE - 30)° = 40° ( multiply both sides by 2 )

AE - 30 = 80 ( add 30 to both sides )

AE = 110° → D
