Detailed Solution
Download Solution PDFகுறுகிய தந்திரம்∶
நாம் அறிந்தபடி,
∠A + ∠B = 2∠CED
⇒ 32° + ∠B = 2 × 43°
⇒ ∠B = 86° – 32° = 54°
விரிவான தீர்வு∶
ΔCED இல்
∠C/2 + ∠D/2 + ∠CED = 180°
⇒ ∠C/2 + ∠D/2 + 43° = 180°
⇒ ∠C/2 + ∠D/2 = 180° – 43° = 137°
⇒ ∠C + ∠D = 137° × 2 = 274°
நாம் அறிந்தபடி,
∠A + ∠B + ∠C + ∠D = 360°
⇒ 32° + ∠B + 274° = 360°
⇒ ∠B = 360° – 306° = 54°
