Answer:
x=22
Step-by-step explanation:
The angles are vertical angles, therefore they are congruent. We can set them equal to each other.
6x-10=5x+12
Now, solve for x. First, move all the variables to one side of the equation, and all the numbers to the other.
Subtract 5x from both sides
6x-5x-10=5x-5x+12
x-10=12
Add 10 to both sides
x-10+10=12+10
x=22
