To find the value of $x$, we can analyze the given triangles:

Triangle $ABC$:

1. The angles in a triangle add up to $180^\circ$.
2. From the diagram:
   • $\angle A = 88^\circ$,
   • $\angle B = 22x + 22$,
   • $\angle C$ is unknown, but we can calculate it.

The sum of the angles is: $\angle A + \angle B + \angle C = 180^\circ$

Substituting the known values: $88 + (22x + 22) + \angle C = 180$

Simplify: $110 + 22x + \angle C = 180$

\angle C = 70 - 22x \tag{1}

Triangle $PQR$:

1. From the diagram:
   • $\angle P = 44^\circ$,
   • $\angle Q = 104^\circ$,
   • $\angle R$ is unknown.

Using the sum of angles in a triangle: $\angle P + \angle Q + \angle R = 180^\circ$

Substitute the known values: $44 + 104 + \angle R = 180$

Simplify: \angle R = 32^\circ \tag{2}

Proportional Triangles:

Since triangles $ABC$ and $PQR$ are similar (angles match), their corresponding angles and sides are proportional. Specifically: $\angle C = \angle R$

Substitute $\angle C = 70 - 22x$ from Equation (1) and $\angle R = 32^\circ$ from Equation (2): $70 - 22x = 32$

Solve for $x$: $22x = 70 - 32$

$22x = 38$

$x = \frac{38}{22} = \frac{19}{11} \approx 1.73$

Final Answer:

$x = \frac{19}{11} \; \text{or approximately } 1.73$
