Step-by-step explanation:

angle of straight line is 180

180=angle(pos) + angle(ros)+angle (roq)

180-angle(pos)-angle(roq)=angle(ros)

angle(ros)=180-angle(pos)-angle(roq)

(or)method 1

angel(ros)=angle(QoS)-90

angel(ros)=angle(QoS)-(angel(ros)+angle(pos))

angle(ros)=angle(QoS)-angle(ros)-angle(pos)

2angle(ros)=angle(QoS)-angle (pos)

angle (ros)=1/2 *(angel(QoS)-angle(pos))

(or)method 2

angel(ros)=180-angle(pos)-angle (roq)..

angle(ros)=180-angle(pos)-90

angle(ros)=90-angel(pos)

multiplying 2 on both sides

2angle(ros)=180-2angle(pos)

2angle(ros)=180-angel(pos)-angel(pos)

2angle(ros)=angle(qos)-angle(pos)

angle(ros)=1/2 * angle(QoS)-angle(pos)
