Answer:
A. [tex]m\angle QNR=96^{\circ}[/tex]
Step-by-step explanation:
We have been given that ray NS bisects angle QNR. The measure of angle QN is 48 degrees. We are asked to find the measure of angle QNR.
Since ray NS bisects angle QNR, so it will divide angle QNR into two equal angles.
The measure of angle QNR will be two times the measure of angle QNS.
[tex]m\angle QNR=2\times m\angle QNS[/tex]
[tex]m\angle QNR=2\times 48^{\circ}[/tex]
[tex]m\angle QNR=96^{\circ}[/tex]
Therefore, the measure of angle QNR is 96 degrees.
