Answer:

x=27

Step-by-step explanation:

We know that the vertical opposite angles are equal when two lines intersect each other at a point.

So two angles are equal. We equate the angles and solve for x

[tex]4x+7=5(x-4)[/tex]

To solve for x we multiply 5 inside the parenthesis

[tex]4x+7=5x-20[/tex]

Subtract 4x from both sides

[tex]7=x-20[/tex]

Now add 20 on both sides

[tex]27=x[/tex]

The value of x is 27
