Answer:
Option C is correct
[tex]\angle R[/tex]
Step-by-step explanation:
Definition:
Angle subtended by the chord on the same segment are equal.
From the given figure:
[tex]\angle Q =47^{\circ}[/tex]
Draw a line that join S and T.
Here, ST line segment represents Chord.
[tex]\angle R[/tex] and [tex]\angle Q[/tex] subtended by the chord ST on the same segment
then by above definition:
[tex]\angle R = \angle Q = 47^{\circ}[/tex]
Therefore, the angle R measures 47 degrees.
