bRAINIEST ME
Step-by-step explanation:
the angles marked with red arcs
have sides made from the same two straight lines,
but the only part they have in common is their vertex.
In English, I have seen them called "vertical angles."
The "vertical" part refers to their vertex.
In Spanish, I have heard them called "opuestos por el vertice."
Teachers like you to remember the names they told you in class.
Whatever you call them, those angles are mirror images of each other,
so by flipping (or rotating around the vertex) one of those angles,
it can be exactly superimposed on the other.
A teacher would call them "congruent."
That means that they have the same measure, so
6x=x%2B90 and that is the equation to solve to find x.
Solving:
6x=x%2B90
6x-x=x%2B90-x
5x=90
x=90%2F5
x=18
So, the measure of each of those angles is
%2890%2Bx%29%5Eo=%2890%2B18%29%5Eo=highlight%28108%5Eo%29 .
