Question

1. find x. (2x - 8)° (x + 19)° x = ____

Explanation:

Step1: Set up the equation

Vertical - angles are equal. So, $2x - 8=x + 15$.

Step2: Isolate the variable

Subtract $x$ from both sides: $2x-x-8=x - x+15$, which simplifies to $x - 8=15$.

Step3: Solve for $x$

Add 8 to both sides: $x-8 + 8=15 + 8$. So, $x=23$.

Answer:

$23$
