Question

For what value of x will the lines l and m be parallel to each other if u answer it fast as fast u can I will mark as brainliest please fast​

Answer 1

Answer :-

The value of x is 30.

Step-by-step explanation:

To Find :-

• The value of x

★ Solution

Given that,

• l and m are parallel lines and t is the transversal.

∴ (3x - 20)° = (2x + 10)° . . . . corresponding angles.

⇒ (3x - 20) = (2x + 10)

⇒ 3x - 20 = 2x + 10

⇒ 3x - 2x = 10 + 20

⇒ x = 30

We got, The value of x as 30.

Hence, The value of x is 30.

Now,

V E R I F I C A T I O N :-

• (3x - 20) = (2x + 10)

By putting the value of x in both L.H.S and R.H.S :-

L.H.S :-

⇒ (3x - 20)

⇒ (3*30 - 20)

⇒ (90 - 20)

⇒ 70

R.H.S :-

⇒ (2x + 10)

⇒ (2*30 + 10)

⇒ (60 + 10)

⇒ 70

∴ L.H.S = R.H.S

Hence, Verified!
