WebSo the law of cosines tells us that 20-squared is equal to A-squared, so that's 50 squared, plus B-squared, plus 60 squared, minus two times A B. So minus two times 50, times 60, times 60, times the cosine of theta. This works out well for us because they've given us everything. There's really only one unknown. WebThe Law of Sines (or the Sine rule) is the relationship between the sides and angles of a triangle. It states that the ratio of the length of one side of a triangle to the sine of the angle opposite to it, is the same for all the sides and all the …

Webc 2 = a 2 + b 2 - 2ab * cos (C) Once you have the length of the third side, you can use the Law of Sines to find the remaining angles (A and B) as: a/sin (A) = b/sin (B) = c/sin (C) = 2R. Where R is the circumradius of the triangle. You can also use the given side lengths and angles to find the area of the triangle using Heron's formula or ...
