AB = 8.4 సెం.మీ, మరియు AC = 5.6 సెం.మీ, DC = 2.8 సెం.మీ
ఉపయోగించిన భావన:
త్రిభుజం యొక్క కోణ సమద్విఖండన రేఖ, ఎదుటి భుజాన్ని త్రిభుజం యొక్క మిగిలిన రెండు భుజాలకు అనులోమానుపాతంలో ఉన్న రెండు భాగాలుగా విభజిస్తుంది.
గణన:
భావన ప్రకారం,
AB/AC = BD/DC
⇒ 8.4/5.6 = BD/2.8
⇒ 8.4/2 = BD
⇒ 4.2 = BD
కాబట్టి, BD + DC = BC
BC = 4.2 + 2.8
⇒ 7 సెం.మీ
∴ భుజం BC పొడవు 7 సెం.మీ.
