संकल्पना:
पूरक कोनांची बेरीज = 180°
त्रिकोणाच्या सर्व अंतर्गत कोनांची बेरीज = 180°
गणना:
⇒ ΔABC मध्ये
⇒ ∠ADB + ∠ADC = 180°
⇒ 108° + ∠ADC = 180°
⇒ ∠ADC = 180° - 108° = 72°
⇒ ΔADC मध्ये
⇒ ∠ADC + ∠ACD + ∠DAC = 180°
⇒ 72° + x° + 48° = 180°
⇒ x° = 180° - 48° - 72° = 180° - 120° = 60°
∴ आवश्यक उत्तर 60° असेल.
