WebFeb 10, 2024 · Besides the two sides, you need to know one of the inner angles of the triangle. Let's say it's the angle γ = 30° between the sides 5 and 6. Then: Recall the law of cosines formula c² = a² + b² - 2ab × cos (γ) Plug in the values a = 5, b = 6, γ = 30°. We obtain c² = 25 + 36 - 2 × 5 × 6 × cos (30) ≈ 9. Therefore, c ≈ 3.
