Final answer:
The measure of angle COD is expressed as 2x+12. To find its numerical value, additional information regarding the relationship to angle AOE or the value of x is required.
Step-by-step explanation:
The student is asking to find the measure of angle COD given the measure of angle AOE as 4x-18, and the measure of angle COD as 2x+12. It seems like the problem involves a relationship between the two angles, potentially that they are equal or supplementary depending on the context, which is not provided. However, to directly answer the student's question without additional information, we can simply state that the measure of angle COD is 2x+12. Without knowing the relation between angle AOE and angle COD, or the value of x, we cannot provide a numerical measure for angle COD. If there is an implied relationship between the two, the student would need to provide that information to find the precise measure of angle COD.
