Download Solution PDFఇవ్వబడింది:
AB = AC మరియు ∠BAC = 48°
ఉపయోగించిన భావన:
చక్రీయ చతుర్భుజం యొక్క వ్యతిరేక కోణాల మొత్తం = 180°
లెక్కింపు:
∠ABC = ∠ACB [∵ AB = AC ]
∠BAC + ∠ABC + ∠ACB = 180°
కాబట్టి, ∠ABC = ∠ACB = (180° - 48°)/2 = 132°/2 = 66°
అలాగే, ∠ADC + ∠ABC = 180°
⇒ ∠ADC + 66° = 180°
⇒ ∠ADC = 180° - 66° = 114°
∴ ∠ADC యొక్క కొలత 114°
