1. Problem Description
The image shows a circle divided into sectors. We are given the degree measures of three sectors: , , and . We need to determine the measure of the central angle of the remaining sector, labeled 'A'.
2. Solution Steps
The sum of the central angles of all sectors in a circle is . Let be the measure of the central angle of sector A.
We can write the equation:
3. Final Answer
The measure of the central angle of sector A is .
