WebStep 2: The corresponding sides that involve x x are AB = 30 A B = 30 and ED= x E D = x, so we form the ratio of them and set it equal to the ratio found in Step 1: 30 x = 15 6 30 x = 15 6. Step 3 ... WebFeb 10, 2024 · a² = b² + c² - 2bc × cos (α) b² = a² + c² - 2ac × cos (β) c² = a² + b² - 2ab × cos (γ) For a right triangle, the angle gamma, which is the angle between legs a and b, is equal to 90°. The cosine of 90° = 0, so in that special case, the law of cosines formula is reduced to the well-known equation of Pythagorean theorem:
