WebTogether with the law of sines, ... Considering that a, b and c are the 3 sides of the triangle opposite to the angles A, B and C as presented within the following figure, the law of cosines states that: In order to solve for the three sides (a, b and c) you should be using these equations: a 2 = b 2 + c 2 - 2bc*cos(A) a = √[b 2 + c 2 - 2bc ... WebWhen using similar triangles, their sides are proportional. If two triangles have two congruent angles, then the triangles are similar. So, if you have a 30-60-90 triangle …

The following are examples of how to solve a problem using the law of sines. Given: side a = 20, side c = 24, and angle γ = 40°. Angle α is desired. Using the law of sines, we conclude that Note that the potential solution α = 147.61° is excluded because that would necessarily give α + β + γ > 180°. WebLaw of sines states that in any right triangle, the sides are proportional to the sine of their opposite angles or the sine of the angles is proportional to their opposite sides.
