Answer:
X=11
Step-by-step explanation:
(10x+30)=140
-30 both sides
10x=110
Divide 10 both sides
X=11
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

Y = 2x
y = 2*(-15) = -30 . . . . . selection A is appropriate
