The image you've provided shows a quadrilateral with angles and side lengths labeled, and we are tasked with finding the range of values for $x$. Let's break down the problem and solve it step by step.

Problem Overview:

• One side of the quadrilateral is labeled as $10$.
• Another side is labeled $2x - 4$.
• The diagram shows two known angles: 45° and 60°.

From the layout of the diagram, it appears this is likely a problem involving the triangle inequality or some other geometric property, such as properties of a kite or an isosceles triangle (as one side is marked congruent).

Let's proceed by identifying potential constraints based on the given sides and angles. Since no immediate triangle information is given (aside from partial congruence), we will analyze it with properties like the triangle inequality for valid ranges.

Analysis:

• Triangle Inequality Theorem: The sum of the lengths of any two sides of a triangle must be greater than the third side.

We will apply this theorem to the triangle with angles 60°, 45°, and the sides labeled $10$ and $2x - 4$.

Step-by-Step Calculation:

1. First inequality: $10 + (2x - 4) > 0$ \Rightarrow 2x - 4 > -10 \quad \text{(This condition is trivial, but confirms validity for x)} Simplifying: $2x > -6 \quad \Rightarrow x > -3$

2. Second inequality (triangle bounds): We know the sum of two sides must be greater than the third. Since more geometric constraints or additional rules will likely help with the bounds further,
