Answer 1

ii) 30°

Step-by-step explanation:

We can say that,

2y + 60° = 4y [alternate exterior angles]

=> 60° = 4y - 2y

=> 60° = 2y

=> 60°/2 = y

=> 30° = y

=> y = 30°

Hence ths value of y = 30°

hope it helps.

Answer 2

Answer:

y=30

Step-by-step explanation:

For l || m,

4y=2y+60 (since alternate exterior angles are equal when two parallel line are intersected by a transversal)

or, 4y-2y=60

or, 2y=60

or, y=30

Therefore, y=30
