Download Solution PDFदिया गया है:
∠CAB = 40°, ∠BDC = x°
अवधारणा:
समचतुर्भुज ABCD में, सभी भुजाएँ बराबर होती हैं।
समचतुर्भुज के आसन्न कोणों का योग 180° के बराबर होता है।
गणना:
∠D = 2 × ∠BDC = 2x [समचतुर्भुज में विकर्ण कोणों को समद्विभाजित करते हैं]
∠A = 2 × ∠CAB = 2 × 40 = 80°
अब,
∠CAB + ∠D = 180°
⇒ 80°+ 2x = 180°
⇒ x = 100/2 = 50°
∴ x का मान 50° है।
