Splet06. sep. 2024 · The law of cosines states that: c^2 = a^2 + b^2 – 2ab * cos (C) This means that if you know the lengths of two sides of a triangle, as well as the angle between them (angle C in the equation), you can use the law of cosines to find the length of the third side.Splet25. jan. 2024 · That’s what the Law of Cosines does – it allows us to find the third length of any triangle. Here’s the formula: c 2 = a 2 + b 2 − 2 a b ⋅ cos ( C) As you can see from the end of the formula we need one more piece of information than the Pythagorean Theorem requires – we need the measure of an angle.
