Solution

Concept: 1 Mark
Application: 1.5 Marks
Answer: 0.5 Mark each

ROS is a straight line.

ROP+POT+TOS=180

4b+75+b=180

5b+75=180

5b=18075

b=21

Since,PQ and RS intersect at O.

QOS=POR      [Vertically opposite angles]

a=4b

a=4×21=84

ROQ=POS  (vertically opposite angles)

2c=75+b

2c=75+21

2c=96

c=48
