To find the measure of the reflex angle \( I \), we need a bit more context about how angle \( I \) relates to other angles such as \( X \) or possibly other given angles. A reflex angle is defined as an angle that is greater than 180 degrees and less than 360 degrees.
If you have specific measures of angles or relationships provided (for example, \( I + X = 360° \) if they are adjacent angles), please provide that information. Otherwise, without additional details, we cannot calculate the exact measure of angle \( I \).
Could you please specify the relationship or provide any other angle measures involved?
