WebSecond, if you know all three sides of a triangle, then you can use it to find any angle. For instance, if the three sides are a = 5, b = 6, and c = 7, then the law of cosines says 49 = 25 + 36 – 60 cos C,so cos C = 12/60 = 0.2, and, with the use of a calculator, C = 1.3734 radians = 78.69°. Note:When triangle is obtuse, the cos Cis negative. WebProve that in a triangle A B C, ∠ A = ∠ 2 B, if and only if: a 2 = b ( b + c) where a, b, c are the sides opposite to A, B, C respectively. I attacked the problem using the Law of Sines, and tried to prove that if ∠ A was indeed equal to 2 ∠ B then the above equation would hold true. Then we can prove the converse of this to complete the proof. chucky on youtube https://jirehcharters.com
