WebThe law of cosine is expressed in three different ways. We will use the formula a 2 = b 2 + c 2 - 2bc·cos A, because the required side is opposite to ∠A. Substitute 1.8 for 'b', 2.5 for 'c' and 36º for angle A. a 2 = b 2 + c 2 - 2bc·cosA a 2 = (1.8) 2 + (2.5) 2 - 2 (1.8) (2.5)cos 36º a 2 = 3.24 + 6.25 - (9) (0.8) a 2 = 3.24 + 6.25 - 7.2 a 2 = 2.29 WebThe cosine rule, also known as the law of cosines, relates all 3 sides of a triangle with an angle of a triangle.
