How do you solve the triangle given triangleABC, a=10, b=12, mangleB=30? Trigonometry Triangles and Vectors General Solutions of Triangles 1 Answer sankarankalyanam Feb 26, 2018 color(blue)(hat A = 24.62, hat C = 125.38, c = 19.57 Explanation: color(blue)(a = 10, b = 12, hatB = 30^@ Applying law of sines, hat A = sin ^-1 ((a * sin B)/b) = sin ^-1 ((10 * sin 30)/12) = 24.62^@ hat C = 180 - 30 - 24.62 = 125.38^@ c = (sin C * b)/ sin B = (sin 125.38 * 12) / sin 30 = 19.57 Answer link Related questions How do you use the Pythagorean Theorem, trigonometry functions, the Law of Sines, and the Law of...
