∠YKZ = 112°
സൂത്രവാക്യം:
ഒരു ത്രികോണത്തിന്റെ 3 കോണുകളുടെയും തുക 180°
K ആന്തര കേന്ദ്രത്തിലായതിനാൽ, ∠YKZ = 90° + ∠YXZ/2
കണക്കുകൂട്ടൽ:
△YKZ ൽ
∠XYZ/2 + ∠XZY/2 + ∠YKZ = 180°
⇒ ∠XYZ/2 + ∠XZY/2 + 112° = 180°
⇒ ∠XYZ/2 + ∠XZY/2 = 180° - 112°
⇒ ∠XYZ + ∠XZY = 2 × 68°
⇒ ∠XYZ + ∠XZY = 136°
നമുക്കറിയാവുന്നത് പോലെ
∠YXZ + ∠XYZ + ∠XZY = 180°
⇒ ∠YXZ + 136° = 180°
⇒ ∠YXZ = 180° - 136°
∴ ∠YXZ = 44°
∠YKZ = 90° + ∠YXZ /2
⇒ 112° = 90° + ∠YXZ/2
⇒ ∠YXZ/2 = 112° - 90°
⇒ ∠YXZ = 22° × 2
∴ ∠YXZ = 44°
