POS is a straight line. ( Linear pair ).
The sum of angles formed on a straight line is equal to 180 °. It is also called LINEAR PAIR.
So,
Angle POQ + Angle QOR + Angle ROS = 180 °
60 ° + 5x - 20 ° + 40 ° = 180 °
5x + 80 ° = 180 °
5 x = 180 ° - 80 ° = 100 °
x = 100 ° ÷ 5
x = 20 °
Hence, x = 20 °

Answer:
x=20
Step-by-step explanation:
POS is a straight line. ( Linear pair ).
The sum of angles formed on a straight line is equal to 180 °. It is also called LINEAR PAIR.
So,
Angle POQ + Angle QOR + Angle ROS = 180 °
60 ° + 5x - 20 ° + 40 ° = 180 °
5x + 80 ° = 180 °
5 x = 180 ° - 80 ° = 100 °
x = 100 ° ÷ 5
x = 20 °
Hence, x = 20 °
