Question

Find the value of x for which yhe lines l and m will be parallel to each other in the following figure​

Answer 1

Answer:

x=9

Step-by-step explanation:

Since the lines are parallel,

x value is equal for both

so, 5x+9=4x

Transposing on both side we get,

x= -9

hope it helps you...

Answer 2

Answer:

x=9 ( clockwise direction)

Step-by-step explanation:

As we know that when two parallel lines are cut by a transversal , the resulting alternate interior angles are congruent.

Therefore, 5x+9= 4x ➜ x= -9

Negative angle shows that the angle drawn is clockwise.
