To find the measurement of \( \angle NKI \), we need to go through the construction steps given the initial measurement of \( \angle JKI \).
- The angle \( \angle JKI \) measures 56 degrees.
- Carlos constructs ray \( KM \), which is the angle bisector of \( \angle JKI \). Therefore, \( \angle JKM \) and \( \angle MKI \) are each half of \( \angle JKI \). \[ \angle JKM = \angle MKI = \frac{56^\circ}{2} = 28^\circ \]
- Carlos then constructs ray \( KN \), which is the angle bisector of \( \angle MKI \). Since \( \angle MKI = 28^\circ \), the angles \( \angle MKN \) and \( \angle NKI \) will also be half of \( \angle MKI \). \[ \angle MKN = \angle NKI = \frac{28^\circ}{2} = 14^\circ \]
Therefore, the measurement of \( \angle NKI \) is \( 14^\circ \).
The correct response is: The measurement of \( \angle NKI \) is 14 degrees.
