Explanation:

Step1: Use segment addition postulate

Since \( Y \) is between \( X \) and \( Z \), we have \( XY + YZ = XZ \). Substituting the given values \( XY = 11 \), \( YZ = 4c \), and \( XZ = 83 \), we get the equation \( 11 + 4c = 83 \).

Step2: Solve for \( c \)

Subtract 11 from both sides of the equation: \( 4c = 83 - 11 \). Simplifying the right side gives \( 4c = 72 \). Then divide both sides by 4: \( c = \frac{72}{4} = 18 \).

Step3: Find \( YZ \)

Now that we know \( c = 18 \), substitute \( c \) into the expression for \( YZ \), which is \( 4c \). So \( YZ = 4 \times 18 = 72 \).

Answer:

\( c = 18 \); \( YZ = 72 \)
