Find the measure of the marked angles.
The measure of the angles is
___ degrees

Answer:
43 degrees
Step-by-step explanation:
The angles are vertical angles. All vertical angles are congruent meaning that these 2 expressions can be set equal to each other. Then, solve for x and finally plug x back in to get the answer.
(4x+19)=(6x+7)
4x+12=6x
12=2x
x=6
Now, we can plug 6 into the expression given to show that both angles are 43 degrees.
