Question

find x (2x + 31)° (x + 23)° x = ____

Explanation:

Step1: Set up equation

Vertical - angles are equal. So, \(2x + 31=x + 23\).

Step2: Isolate x - terms

Subtract \(x\) from both sides of the equation: \(2x - x+31=x - x + 23\), which simplifies to \(x+31 = 23\).

Step3: Solve for x

Subtract 31 from both sides: \(x=23 - 31\).

Answer:

\(x=-8\)
