WebConsidering cosine law: ∑ abc(b2 + c2 − a2) = ∑ abc2bccosA a2 + b2 + c2 = 2bccosA + 2cacosB + 2abcosC One possibility is cosA = 0, 2cosB = 1 and 2cosC = √3. Hence A = 90 ∘, B = 60 ∘ and C = 30 ∘. Proof of Uniqueness of the above solution: Rearrange the equality as a quadratic in b: b2 − (a√3)b + (a2 − ac + c2) = 0 WebApr 14, 2024 · At 14/04/2024 08:16:00 the Bureau of Meteorology advised cold and unstable air behind a cold front is passing over the south coast of WA, gradually moving eastwards …
