Final answer:
Without clear information on which angles are opposite each other in the rhombus or additional context, it is not possible to find the value of x solely based on the expressions provided.
Step-by-step explanation:
To find the value of x in a rhombus where the measures of the angles are given by expressions in terms of variables x, y, and z, we can utilize the properties of a rhombus which state that opposite angles are equal. However, the information provided does not specify which angles are opposite to each other in this context. Typically, the sum of the angles in any rhombus will add up to 360 degrees, and if angle 1 and angle 2 are opposite, their measures would equal each other. Without additional information or the ability to identify opposite angles, it is impossible to derive the value of x from the expressions given.
