x=11

------------------------------------------------------------------------------------------------------

Since 140 and 10x+30 are vertical angles, they are equal.

Equation: 140=10x+30

  • Subtract 30 from both sides of the equation.

140=10x

  • Divide both sides of the equation by 10.

You get x=10
