Given Q below, is YQR a minor arc, a major arc, or a semicircle?

Answer:
B. Major arc.
Step-by-step explanation:
We have been given diagram of circle Q. We are asked to determine whether YQR is a minor arc, a major arc, or a semicircle.
Upon looking at our given circle, we can see that major of arc RY is 150 degrees.
We also know that major of all arcs is a circle is equal to 360 degrees. So we can set an equation as:
[tex]\widehat{YQR}+\widehat{RY}=360^{\circ}[/tex]
Upon substituting measure of arc RY, we will get:
[tex]\widehat{YQR}+150^{\circ}=360^{\circ}[/tex]
[tex]\widehat{YQR}+150^{\circ}-150^{\circ}=360^{\circ}-150^{\circ}[/tex]
[tex]\widehat{YQR}=210^{\circ}[/tex]
Since measure of arc is YQR is greater than 180 degree, therefore, arc YQR is a major arc.
