Question

solve for x.

Explanation:

Step1: Identify angle - relationship

The angles $(7x - 4)^{\circ}$ and $73^{\circ}$ are vertical angles. Vertical angles are equal.

Step2: Set up the equation

We set up the equation $7x-4 = 73$.

Step3: Solve the equation for x

Add 4 to both sides of the equation: $7x-4 + 4=73 + 4$, which simplifies to $7x=77$. Then divide both sides by 7: $x=\frac{77}{7}=11$.

Answer:

$11$
