Detailed Solution
Download Solution PDFदिलेले आहे:
∠ABD = 55° आणि ∠ACD = 30°
गणना:
∠BAD = α आणि ∠CAD = β
अशाप्रकारे, ∠BAC = y = α + β
अशाप्रकारे, ΔABD आणि ΔACD संदर्भात,
∠ADB = 180°- α - 55°
∠ADC = 180 ° - β - 30°
बिंदू D साठी,
∠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°
∴ पर्याय (1) योग्य आहे.
