Detailed Solution
Download Solution PDFఇచ్చింది:
∠ABD = 55° మరియు ∠ACD = 30°
గణన:
∠BAD = α మరియు ∠CAD = β
కాబట్టి త్రిభుజం ΔABD మరియు ΔACDని సూచిస్తూ,
∠ADB = 180°- α - 55°
∠ADC = 180 ° - β - 30°
బిందువు D కోసం,
∠ADB +∠ADC + x = 360°
⇒ 180° - α - 55° + 180 °- β - 30° + x = 360 °
⇒ 360 - α - β - 85° + x = 360
⇒ x - (α + β) - 85° = 0
⇒ x - y - 85° = 0
⇒ x -y = 85°
∴ సరైన సమాధానం ఎంపిక (1).
