Final answer:
The reference information provided does not contain equations or facts that pertain to solving for the variables x, y, and z in the context of congruent triangles, thus making it impossible to determine their values.
Step-by-step explanation:
To find the values of x, y, and z given that ∆PRS ≅ ∆CFH, typically, we would need additional information regarding the relationships between the sides or angles of the triangles. However, based on the provided reference information, we cannot conclusively determine the values of x, y, and z because the reference does not contain any equations or facts directly relating to these variables within the context of congruent triangles.
The provided reference contains isolated equations and statements that do not pertain to solving for variables in congruent triangles. Therefore, without the appropriate context or supporting information, we are unable to calculate the precise values of x, y, and z in this situation.
