The sides of a triangle are \(5\;{\rm{cm}},7\;{\rm{cm}},\) and \(8\;{\rm{cm}}.\) Find the measure of the middle-sized angle.Ans: The middle-sized angle in a triangle lies opposite the middle-sized side.Therefore, the angle lies opposite to 7-cm side.Cosine law is stated as, \({c^2} = {a^2} + {b^2} 2ab \cos C\)\(\therefore \cos A = \frac{{{5^2} + {8^2} {7^2}}}{{2 \times 5 \times 8}}\)\( \cos A = \frac{{25 + 64 49}}{{80}}\)\( \cos A = \frac{{40}}{{80}} = 0.5\)\( \Rightarrow A = {\cos ^{ 1}}\left( {0.5} \right)\)\(\therefore A = {60^{\rm{o}}}\). Describe the relationship among the measures of the angles of triangle ABC ? The third angle in this example is 40 degrees. For each triangle, we know that, \( \Rightarrow \sin A = \frac{{a\sin B}}{b}\), \(\frac{a}{{\sin A}} = \frac{b}{{ \sin B}}\), \(\frac{b}{{ \sin B}} = \frac{c}{{ \sin C}}\), \(\frac{a}{{ \sin A}} = \frac{b}{{ \sin B}} = \frac{c}{{ \sin C}}\).
