Question

12. For what value of x will the lines l and m be parallel to each other? ​

Answer 1

Answer:

I hope this will help:)

Step-by-step explanation:

For the lines l and m to be parallel, Corresponding angles are parallel,

⇒7x−20=3x+2

⇒ 7x-3x=20+20

⇒ 4x=40

⇒ x=10°

ans-d-10°

Answer 2

Answer:

The Correct Answer is Option (d): x = 10

Step-by-step explanation:

Apply the concept of corresponding angles in parallel lines:

Corresponding angles are equal in parallel lines with transversal

Therefore,

7x - 20 = 3x + 20

7x - 3x - 20 = 20

4x - 20 = 20

4x = 20 + 20

4x = 40

x = 40/4

x = 10 Degrees
