WebAnswer: Let ABC be a triangle with A = 3B and a = 2b. Using the law of sines, we take: a/(sinA) = b/(sinB) => 2b/(sin(3B)) = b/(sinB) => 2sinB = sin(3B) => 2sinB = 3 ...

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°.
