The three angles around a point are in the ratio 2 : 3 : 7. What is the size of the reflex angle among them?

Class 7Angles Around a PointLines and Angles
  • A240°
  • B210°
  • C150°
  • D180°

Step-by-Step Solution

2 + 3 + 7 = 12 parts = 360°, so 1 part = 30°. Angles: 60°, 90°, 210°. Only 210° is more than 180°, so it is the reflex angle.
Answer: B) 210°
