WEBUse The Law of Cosines to find side a first: a 2 = b 2 + c 2 − 2bc cosA. a 2 = 5 2 + 7 2 − 2 × 5 × 7 × cos (49°) a 2 = 25 + 49 − 70 × cos (49°) a 2 = 74 − 70 × 0.6560... a 2 = 74 − 45.924... = 28.075... a = √28.075... a = 5.298... a = 5.30 to 2 decimal places. Now we use the The Law of Sines to find the smaller of the other two angles.

WEBFeb 6, 2024 · Law of Cosines. If a, b and c are the lengths of the legs of a triangle opposite to the angles A, B and C respectively; then the law of cosines states: a2 = b2 +c2 − 2bc cos A a 2 = b 2 + c 2 − 2 b c cos. . A. b2 = a2 +c2 − 2ac cos B b 2 = a 2 + c 2 − 2 a c cos. . B. c2 = a2 +b2 − 2ab cos C c 2 = a 2 + b 2 − 2 a b cos.

WEBJun 15, 2021 · Theorem 2.3.1: Law of Cosines. Given a triangle with angle-side opposite pairs (α, a), (β, b) and (γ, c), the following equations hold. a2 = b2 + c2 − 2bccos(α) b2 = a2 + c2 − 2accos(β) c2 = a2 + b2 − 2abcos(γ) or, solving for the cosine in each equation, we have. cos(α) = b2 + c2 − a2 2bc cos(β) = a2 + c2 − b2 2ac cos(γ) = a2 + b2 − c2 2ab.
