Question: Find the measure, to the nearest degree, of each angle of a triangle with sides of the given lengths. 26, 35, 40 Hi Nikki,
Two of the identities in trigonometry that are very useful and worth remembering are the Law of Sines and the Law of Cosines. In the diagram above a is the length of the side BC, b is the length of CA and c is the length of AB. Law of Sines: Law of Cosines a^{2} = b^{2} + c^{2}  2bc cos A
In your problem you have the three side lengths and you are looking for the angles. In this case the Law of Cosines is appropriate since knowledge of a, b and c will allow you to solve for the angles. In particular if a = 26, b = 35 and c = 40 then Harley
