Answer:

x = 50

Step-by-step explanation:

these are vertical angles meaning they are congruent so

[2(x+10)] = (3x-30) then use distributive property

(2x+20) = (3x-30) subtract 2x from both sides

20 = x - 30 add 30 to both sides

x = 50

Answer:

x = 50

Step-by-step explanation:

We know that 2(x+10) = (3x-30) because it is on opposite sides of an "x".

We just set them equal to each other and solve for x!

2(x+10) = 3x - 30

2x + 20 = 3x - 30

20 = x - 30

50 = x
