SSC CHSL Similar 13 Nov S2 Set 2 – Q064

Question:

A designer creates a regular polygonal logo with each internal angle 140°. How many sides does it have?

एक डिजाइनर प्रत्येक आंतरिक कोण 140° वाला एक सम बहुभुज लोगो बनाता है। इसकी कितनी भुजाएं हैं?

Options:

  • 8
  • 9
  • 10
  • 12
  • 8
  • 9
  • 10
  • 12

Correct Answer: b)

Explanation:

Exterior angle = \(180^\circ – 140^\circ = 40^\circ\).
Number of sides \(n = \dfrac{360^\circ}{40^\circ} = 9\).

बाह्य कोण = \(180^\circ – 140^\circ = 40^\circ\)।
भुजाओं की संख्या \(n = \dfrac{360^\circ}{40^\circ} = 9\)।
