Detailed Solution
Download Solution PDFகொடுக்கப்பட்டது:
∠ABD = 55° மற்றும் ∠ACD = 30°
கணக்கீடு:
∠BAD = α மற்றும் ∠CAD = β
எனவே ΔABD மற்றும் ΔACD முக்கோணத்தைப் பொருத்து,
∠ADB = 180°- α - 55°
∠ADC = 180 ° - β - 30°
புள்ளி Dக்கு,
∠ADB +∠ADC + x = 360°
⇒ 180° - α - 55° + 180 °- β - 30° + x = 360 °
⇒ x -y = 85°
