Answer 2

Step-by-step explanation:4b+2c=180°..........angles in linear pair4b=180°-2c............(1)

2c + a=180°..........angles in linear pair

a =180°-2c.............(2)

4b=a........(3)

4b+b+75°=180°......angles in linear pair

5b+75°=180°

5b=105°

b=105°/5

b=21°

put b=21° in equation3

4b=a

4×21=a

a=84°

put a=84° in equation

2a=180°-2c

2c=180°-a

2c=180°-84°

2c=96°c=96°/2c=48°

The values of a,b and c are 21°,48° and 84°.
