Final answer:
Without the provided picture or further context, it's not possible to accurately determine the remaining angle measures based on the information that angle m23 equals 112º.
Step-by-step explanation:
To find the remaining angle measures when given that angle m23 = 112º, we can consider the properties of angles and circles. For example, if angle m23 is an interior angle of a polygon or is adjacent to another angle on a straight line, we could use the sum of the angles in a polygon or the fact that angles on a straight line add up to 180º to find the missing angle measures. However, the question does not provide enough context or a picture to determine which mathematical rules to apply. Therefore, we cannot calculate the remaining angles without additional information.
