Questions & Step-by-Step Solutions

In a regular polygon, if the measure of each exterior angle is 30 degrees, how many sides does the polygon have? (2023)
  • Step 1: Understand that the exterior angle of a regular polygon can be calculated using the formula: 360/n, where n is the number of sides.
  • Step 2: We know from the question that each exterior angle measures 30 degrees.
  • Step 3: Set up the equation using the formula: 360/n = 30.
  • Step 4: To find n, we need to rearrange the equation. Multiply both sides by n: 360 = 30n.
  • Step 5: Now, divide both sides by 30 to solve for n: n = 360/30.
  • Step 6: Calculate the right side: n = 12.
