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
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
