Detailed Solution
Download Solution PDFপ্রদত্ত:
AB = 8.4 সেমি, এবং AC = 5.6 সেমি, DC = 2.8 সেমি
অনুসৃত ধারণা:
ত্রিভুজের কোণ সমদ্বিখণ্ডক বিপরীত বাহুকে দুটি অংশে ভাগ করে যা ত্রিভুজের অন্যান্য দুটি বাহুর সাথে সমানুপাতী।
গণনা:
ধারণা অনুযায়ী,
AB/AC = BD/DC
⇒ 8.4/5.6 = BD/2.8
⇒ 8.4/2 = BD
⇒ 4.2 = BD
তাই, BD + DC = BC
BC = 4.2 + 2.8
⇒ 7 সেমি
∴ তাই BC বাহুর দৈর্ঘ্য 7 সেমি হবে।.
