What is the value of x?
Enter your answer in the box.

Vertical angles are equal
so
3x - 3 = 6(x - 10)
3x - 3 = 6x - 60
-3x = -57
x = 19
answer
x = 19
The 2 equations are vertical angles, which mean they would be the same.
Set the two equations to equal and solve for x.
3x-3 = 6(x-10)
First use the distributive property for the right side:
3x-3 = 6x-60
Add 3 to each side:
3x = 6x -57
Subtract 6x from each side:
-3x = -57
Divide both sides by -3
X = -57 / -3
X = 19
