How to fill out law of cosines sas

How to fill out law of cosines sas:

1. Start by identifying the side lengths and angles of the triangle. Label the sides as a, b, and c, and the angles opposite these sides as A, B, and C, respectively.
2. Determine the values that are known. The law of cosines can be used to find a missing side length or angle in a triangle if you know the lengths of two sides and the included angle, or if you know the lengths of all three sides.
3. Choose the appropriate formula from the law of cosines. For solving a missing side length, use the formula: c^2 = a^2 + b^2 - 2abcos(C). If you are trying to find a missing angle, use the formula: cos(C) = (a^2 + b^2 - c^2) / 2ab.
4. Substitute the known values into the formula and solve for the unknown.
5. If necessary, apply trigonometric functions to find the desired angle measure. For example, if you found the cosine of an angle, you can use the inverse cosine function (cos^-1) to determine the angle measure.
6. Double-check your calculations to ensure accuracy.
