WebLaw of Sines:a/sin A = b/sin B = c/sin C Example: Calculate angle B. 24/7 Customer Support At 24/7 Customer Help, we're always here to help you with your questions and concerns. WebTo find: The angle at A. We know that the sides opposite to A, B, and C are represented by a, b, and c respectively. So we have: a = 10 in; b = 7 in; and c = 5 in. Since we know all three sides, we have to use the law of cosines to find the angle at A. a 2 = b 2 + c 2 - 2bc cos A 10 2 = 7 2 + 5 2 - 2 (7) (5) cos A 100 = 49 + 25 - 70 cos A

WebIn graph perspective, positive cosine means acute angle(Q1) while negative cosine means obtuse angle(Q2). But with sine we have to test if the angle is in Q1 or Q2 since it has the same sine values of 0.987. Hence, we calculate which degree of the two adds up to 180. Therefore, as mentioned by others, it is advisable to use law of cosines.
