ఇచ్చినది:

∠CAB = 40 °, ∠BDC = x°

భావన:

రాంబస్ ABCDలో, అన్ని వైపులా సమానంగా ఉంటాయి.

రాంబస్ యొక్క ప్రక్కనే ఉన్న కోణాల మొత్తం 180°కి సమానం

గణన:

∠D = 2 × ∠BDC = 2x [ వికర్ణాలు రాంబస్‌లోని కోణాలను విభజిస్తాయి]

∠A = 2 × ∠CAB = 2 × 40 = 80°

ఇప్పుడు,

∠CAB + ∠D = 180°

⇒ 80°+ 2x = 180°

⇒ x = 100/2 = 50°

∴ x విలువ 50°.
