X< -4
You need to do inverse operations and add 12 to both sides.
that would be the letter d :)
each value of x has a unique value of y
The pair of vertically opposite angles are ∠1 and ∠3 and ∠4 and ∠2.
<h3>What is vertically opposite angles?</h3>

Vertically opposite angles share the same vertex point.
In other words, vertically opposite angles are angles that are opposite one another at a specific vertex and are created by two straight intersecting lines
Vertically opposite angles are congruent to each other.
Therefore, the pair of vertical angles are as follows:
