Solve Triangles in Your Head with the Law of Cosines Formula
Conclusion
The formula works by using the squared values of the sides and the cosine of an angle to calculate the length of the remaining side.
- Let's say we have a triangle with sides a = 3cm, b = 4cm, and angle C = 60°. We can plug these values into the formula: c² = 3² + 4² - 234 * cos(60°). Solving for c, we get c = √(9 + 16 - 24 * 0.5) = √(9 + 16 - 12) = √13.
