Answer:
The minor arc PR is 42 degrees
Step-by-step explanation:
The picture of the question in the attached figure
we know that
The inscribed angle is half that of the arc comprising
so
[tex]m\angle PSR=\frac{1}{2}(arc\ PR)[/tex]
we have
[tex]m\angle PSR=21^o[/tex]
substitute
[tex]21^o=\frac{1}{2}(arc\ PR)[/tex]
[tex]arc\ PR=21(2)=42^o[/tex]
Remember that the minor arc in a circle is less than 180 degrees
therefore
The minor arc PR is 42 degrees
