To find the measurement of angle \( \angle NKI \), we first need to understand how angles are bisected through the construction.

  1. We know that \( \angle JKI \) measures 56 degrees.

  2. Carlos constructs the angle bisector \( KM \) of \( \angle JKI \), which means that \( \angle JKM \) and \( \angle MKI \) are both half of \( \angle JKI \).

    Therefore, each of those angles measures: \[ \angle JKM = \angle MKI = \frac{56}{2} = 28 \text{ degrees} \]

  3. Next, he constructs the angle bisector \( KN \) of \( \angle MKI \). \( \angle MKI \) measures 28 degrees, so when he bisects it, we have: \[ \angle NKI = \angle MKI / 2 = \frac{28}{2} = 14 \text{ degrees} \]

Thus, the measurement of \( \angle NKI \) is 14 degrees.

The correct response is: "The measurement of angle \( NKI \) is 14 degrees."
