To find the measure of each central angle when a circle is divided into 10 equal parts, you can use the formula:

Calculating the Central Angle

The total angle in a circle is 360 degrees. To determine the angle for each part, divide 360 by the number of parts:

  • Number of parts: 10
  • Calculation: 360° ÷ 10 = 36°

Final Answer

Each central angle measures 36°. Therefore, the correct option is (c) 36°.
