Question

look at the diagram. which equation can be used to solve for x? 6x + 64 = 90 6x - 4 = 68 6x - 72 = 180 2x = 68 solve for x. x = submit

Explanation:

Step1: Identify Vertical Angles

The angles \(68^\circ\) and \((6x - 4)^\circ\) are vertical angles, so they are equal. Thus, we set up the equation \(6x - 4 = 68\).

Step2: Solve for \(x\)

Add 4 to both sides of the equation: \(6x - 4 + 4 = 68 + 4\)
Simplify: \(6x = 72\)
Divide both sides by 6: \(x=\frac{72}{6}\)
Simplify: \(x = 12\)

Answer:

12
