Answer:

x = 20

Step-by-step explanation:

First you set the two equations equal because vertical angles are congruent.

Then you get the equation 3x + 50 = 6x - 10

To solve the equation, you first add 10 to get: 3x + 60 = 6x

Next you subtract 3x to get: 60 = 3x

Then you divide each side by 3 to get x = 20
