Explanation:

Step1: Find the vertical angle

The angle vertical to \(163^{\circ}\) is also \(163^{\circ}\).

Step2: Set up the equation

Since the sum of angles around a point is \(360^{\circ}\), and we have a straight - line pair (but here considering the full - circle sum of angles around a point, or using the fact that the non - overlapping angles sum up. The sum of the three angles \((3x)^{\circ}+(9x - 5)^{\circ}+163^{\circ}=180^{\circ}\) (because they form a linear pair with the vertical - angle concept, the sum of adjacent angles on a straight line is \(180^{\circ}\)).
\[3x+9x-5 + 163=180\]

Step3: Simplify the equation

Combine like terms:
\[12x+158 = 180\]
Subtract \(158\) from both sides:
\[12x=180 - 158\]
\[12x=22\]

Step4: Solve for \(x\)

\[x=\frac{22}{12}=\frac{11}{6}\approx1.83\] (This is wrong. Wait, no, actually, the correct approach: The angle adjacent to \(163^{\circ}\) is \(180 - 163=17^{\circ}\). Then \(3x+9x - 5=17\) (because the three angles \(17^{\circ},3x^{\circ},(9x - 5)^{\circ}\) form a straight line).

Answer:

Step1: Find the vertical angle

The angle vertical to \(163^{\circ}\) is also \(163^{\circ}\).

Step2: Set up the equation

Since the sum of angles around a point is \(360^{\circ}\), and we have a straight - line pair (but here considering the full - circle sum of angles around a point, or using the fact that the non - overlapping angles sum up. The sum of the three angles \((3x)^{\circ}+(9x - 5)^{\circ}+163^{\circ}=180^{\circ}\) (because they form a linear pair with the vertical - angle concept, the sum of adjacent angles on a straight line is \(180^{\circ}\)).

$$3x+9x-5 + 163=180$$

Step3: Simplify the equation

Combine like terms:

$$12x+158 = 180$$

Subtract \(158\) from both sides:

$$12x=180 - 158$$

$$12x=22$$

Step4: Solve for \(x\)

$$x=\frac{22}{12}=\frac{11}{6}\approx1.83$$

$$12x=17 + 5$$

$$12x=22$$

(No! Wait, correct:
The angle adjacent to \(163^{\circ}\) is \(17^{\circ}\). Then \(3x+(9x - 5)=17\) (sum of angles on a straight line).

$$3x+9x-5=17$$

$$12x=17 + 5$$

$$12x=22$$
