একটি ত্রিভুজের তিনটি কোণ হল (18x + 6º), (10x + 30º), এবং (15x + 15º)
ব্যবহৃত সূত্র:
একটি ত্রিভুজের কোণের সমষ্টি = 180º
গণনা:
(18x + 6) + (10x + 30) + (15x + 15) = 180
⇒ 18x + 10x + 15x + 6 + 30 + 15 = 180
⇒ 43x + 51 = 180
⇒ 43x = 180 - 51
⇒ 43x = 129
⇒ x = 3
কোণ: (18×3 + 6) = 60º, (10×3 + 30) = 60º, (15×3 + 15) = 60º
∴ ত্রিভুজটি হলো সমবাহু।
∴ সঠিক উত্তরটি হল বিকল্প 2.
