Webcos A = sin (90 - A) It is given that sin (90 - A) = 1/2. Hence, cos A = 1/2 Answer: cos A = 1/2. Example 3: In a triangle ABC, AB = c, BC = a, and CA = b. Also, a = 55 units, b = 70 units, and c = 50 units. Find cos A. Solution: Using the cosine formula of law of cosines, cos A = (b 2 + c 2 - a 2) / (2bc) = (70 2 + 50 2 - 55 2) / (2 · 70 · 50) WebFeb 10, 2024 · B = (a × cos (γ), a × sin (γ)) From the distance formula, we can find that: c = √ [ (x₂ - x₁)² + (y₂ - y₁)²] = √ [ (a × cos (γ) - b)² + (a × sin (γ) - 0)²] Thus: c² = a² × cos (γ)² - 2ab × cos (γ) + b² + a² × sin (γ)² c² = b² + a² (sin (γ)² + cos (γ)²) - 2ab × cos (γ) how to set time on lennox icomfort thermostatWeb10.5. =. 0.79.
