Answer 2

$\sf \large{ \underline{Solution- }}$

Here it is given that,

➢ l and m are the two parallel lines and both the lines are intersected by line n.

• Here we have to find the value of x after seeing the diagram.

First of all,

⟹ 3y = 2y + 25°

• [By Alternative angles]

⟹ 3y - 2y = 25°

⟹ y = 25°

Now,

⟹ 2y + 25° = x + 15°

• [By vertically opposite angles]

⟹ 2(25°) + 25° = x + 15°

⟹ 50°+ 25° = x + 15°

⟹ 75° = x + 15°

⟹ 75° - 15°  = x

⟹ 60° = x

Therefore,

• The value of x is 60°
