Download Solution PDFপ্রদত্তঃ প্রতিটি বহিঃস্থ কোণ 24 °
ধারণা:
একটি নিয়মিত বহুভুজের বহিঃস্থ কোণগুলির যোগফল = 360°
ব্যবহৃত সূত্র:
একটি নিয়মিত বহুভুজের প্রতিটি বহিঃস্থ কোণ = 360/n
এবং
কর্ণের সংখ্যা = n(n – 3)/2
যেখানে n = বাহুর সংখ্যা
গণনা:
বাহুর সংখ্যা = 360/24 = 15
সুতরাং,
কর্ণের সংখ্যা = (15 × 12) / 2 = 90Last updated on Jun 9, 2025
