WebIn an acute angled triangle ABC, if sin 2 (A + B – C) =1 and tan (B + C – A) = √3, then what is the value of angle B? An acute angled triangle ABC, such that sin [2 (A + B - C)] = 1 This means that 2 (A + B - C) = 90° Or A + B - C = 45° - - - - - - - - - - - - - - - - (1) Also tan (B + C - A) = (3)½ This means that WebA function is defined on a domain , or a set of inputs. When you talk about a function, you have to talk about its domain and its codomain , or the set the function outputs come from.

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 WebMar 29, 2024 · Transcript. Question 23 In ∆ABC, ˂B = 90° and BD ꓕ AC.
