Move point C so the measure of arc
AC is 50°
What is the measure of ABC?

Answer:
[tex]m\angle ABC=25^o[/tex]
Step-by-step explanation:
we know that
The inscribed angle is half that of the arc comprising
so
[tex]m\angle ABC=\frac{1}{2}[arc\ AC][/tex]
If the measure of arc AC is 50 degrees
then
[tex]m\angle ABC=\frac{1}{2}[50^o]=25^o[/tex]
