4.3 Use 4.2 to determine \( Y Z \), if \( X Z=32 \mathrm{~cm} \)

To solve for \( YZ \) using the information provided, we need to first understand the relationship between the variables \( XZ \), \( YZ \), and any other relevant variables or equations from section 4.2. However, since I don't have access to section 4.2, I will assume that there is a proportional relationship or a specific formula that relates these variables. Let's denote: - \( XZ = 32 \, \text{cm} \) - \( YZ \) is what we want to find. If we assume that there is a direct proportionality or a specific ratio given in section 4.2, we can express it as: \[ \frac{YZ}{XZ} = k \] where \( k \) is a constant derived from section 4.2. If you can provide the specific relationship or formula from section 4.2, I can proceed with the calculations. Otherwise, I can only provide a general approach. Please clarify or provide the necessary details!
