AB = 8.4 सेमी, और AC = 5.6 सेमी, DC = 2.8 सेमी
प्रयुक्त अवधारणा:
त्रिभुज का कोण समद्विभाजक सम्मुख भुजा को त्रिभुज की अन्य दो भुजाओं के समानुपाती दो भागों में विभाजित करता है।
गणना:
अवधारणा के अनुसार,
AB/AC = BD/DC
⇒ 8.4/5.6 = BD/2.8
⇒ 8.4/2 = BD
⇒ 4.2 = BD
इसलिए, BD + DC = BC
BC = 4.2 + 2.8
⇒ 7 सेमी
∴ भुजा BC की लम्बाई 7 सेमी होगी।
