x = 20
Step-by-step explanation:
In this problem, we have a set of vertical angles. We know that vertical angles are congruent, so we just have to set the two expressions equal to each other.
[tex]3x+50=6x-10[/tex]
Subtract 3x from both sides.
[tex]3x-10=50[/tex]
Add 10 to both sides.
[tex]3x=60[/tex]
Divide 60 by 3.
x = 20
