The "Ivan" section represents 45% of the whole circle, and the "Bernard" section (which is not relevant to this question) represents 55%.

Since a circle has 360 degrees, we can find the measure of the central angle in the "Ivan" section as follows:

- Calculate the fraction of the circle represented by the "Ivan" section: 45% = 0.45

- Multiply this fraction by the total number of degrees in a circle: 0.45 x 360 = 162

Therefore, the measure of the central angle in the "Ivan" section is 162 degrees.
