Respuesta :

Since, AB and BC are the same length, the measure of the chord for BC would be 12.5 units

we know that

AB and BC are congruent

That means

[tex]AB=BC[/tex] ----> equation A

we have

[tex]AB=12.5\ units[/tex]

substitute in equation A

[tex]BC=12.5\ units[/tex]

therefore

the answer is the option B

[tex]12.5\ units[/tex]
