Question

In circle Q with

Answer 1

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

$m\angle PSR=\frac{1}{2}(arc\ PR)$

we have

$m\angle PSR=21^o$

substitute

$21^o=\frac{1}{2}(arc\ PR)$

$arc\ PR=21(2)=42^o$

Remember that the minor arc in a circle is less than 180 degrees

therefore

The minor arc PR is 42 degrees
