Law of Sines and Cosines. The entire trigonometry that has been done thus far has dealt with the indirect measurement of sides and angles of right triangles. The calculations were carried out using Pythagorean Theorem and/or Trigonometric Ratios. This process can now be expanded to include oblique triangles.

The Law of Sines is easy to apply, but the Law of Cosines leads to a more straightforward solution. Keep these in mind: The sum of the angles in a triangle is 1800. The longest side is opposite the largest angle, the shortest side opposite the shortest angle, etc. When using the Law of Cosines, any ambiguities are very easy to see and deal with.

We could use Law of Sines or Cosines to find the missing angles, but it is better to use the Law of Cosines since the arccosine function will distinguish between acute and obtuse angles. C = 180 – A – B. SSS. We know the three sides of the triangles. C = 180 – A – B . Example: Solve given a = 11, b = 5 and C = 20(. Solution:

The Law of Sines Now that we have seen the Law of Cosines in action, it is time to explore the Law of Sines. In order to use the Law of Sines to determine the length of a side, we must know the measure of an angle and its corresponding side plus the measure of the corresponding angle of the unknown side.
