Detailed Solution
Download Solution PDFகொடுக்கப்பட்டது:
AB = 10 செ.மீ., மற்றும் AC = 14 செ.மீ
பயன்படுத்தப்பட்ட கருத்து:
ஒரு முக்கோணத்தின் கோண இருமுனையானது முக்கோணத்தின் மற்ற இரண்டு பக்கங்களுக்கு விகிதாசாரமாக எதிர் பக்கத்தை இரண்டு பகுதிகளாக பிரிக்கிறது.
கணக்கீடு:
கருத்தின்படி,
AB/AC = BD/DC
⇒ 10/14 = BD/DC
⇒ 5/7 = BD/DC
எனவே, BD : DC = 5 : 7
இப்போது, BC = 5 + 7
⇒ 12
எனவே, BD : BC = 5 : 12
∴ தேவையான பதில் 5 : 12.
