Respuesta :

D. 132º

1) Given that in this circle crossed by two secant lines we can state the following Theorem:

2) then we can write:

[tex]\begin{gathered} m\angle ABD=\frac{AD\text{ +CE}}{2} \\ 134=\frac{136+CE}{2} \\ 134\text{ }\times2=136+CE \\ 268=136+CE \\ CE\text{ =268-136} \\ CE=132 \end{gathered}[/tex]

So the measure of the arc CE = 132º (D)
