8) In the triangle ABC below, what is the length, in meters, of line AB? Round to the nearest tenth.
(Note: For a triangle with sides of length a, b, and c opposite angles ∠A, ∠B, and ∠C, respectively, the law of sines states (sin∠A)/a = (sin∠B)/b = (sin∠C)/c and the law of cosines states c² = a² + b² − 2ab cos∠C)
