MME Find a Tutor! Buy Revision Cards! The sine rule and the cosine rule are two equations that help us find missing side-lengths and angles in any triangle. They are both expressed according to the triangle on the right, where each letter represents one side-length lower-case and the angle opposite to it upper-case. To answer this question, we have to match up the information in the question to the letters in the formula. The only remaining bit of information is the angle, and looking at the cosine rule formula, we see that this must be the opposite angle to whichever side a is. Like with the cosine rule, we need to match up the letters in the formula with the information in the question.
