What is linear pair?
When two Lines Intersect each other the adjacent angle formed in one/same Line is called Linear Pair and sum of linear pairs are always 180°.
In the Given Figure,
3y and 2x are linear pair.
therefore,
➛3y + 2x = 180°
value of x is 30°
➛3y + 2(30) = 180°
➛3y = 180° - 60°
➛y = 120°/3
→y = 40° Answer.
