Geometry Flashcards Summary
- The value of x is determined to be 98 degrees through the equation 720 - 622 = 98.
- A regular 12-gon, also known as a dodecagon, has an interior angle measurement of 150 degrees calculated using the formula ((n-2) \times 180/n) where n is the number of sides.
- A polygon with each exterior angle measuring 60 degrees will have 6 sides, derived from the formula where the sum of exterior angles equals 360 degrees: (360/60 = 6).
