Detailed Solution
Download Solution PDFदिलेले आहे:
AB = 8.4 सेमी, आणि AC = 5.6 सेमी, DC = 2.8 सेमी
वापरलेली संकल्पना:
त्रिकोणाचा कोनदुभाजक संमुख बाजूला दोन भागांमध्ये विभागतो, जे त्रिकोणाच्या इतर दोन बाजूंशी प्रमाणशीर असतात.
गणना:
संकल्पनेनुसार,
AB/AC = BD/DC
⇒ 8.4/5.6 = BD/2.8
⇒ 8.4/2 = BD
⇒ 4.2 = BD
अशाप्रकारे, BD + DC = BC
BC = 4.2 + 2.8
⇒ 7 सेमी
∴ बाजू BC ची लांबी 7 सेमी असेल.
