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. WebThe law of sines rule can be used to find missing sides or angles in a triangle.
