Solve the triangle given below. Do not round results during calculations. (For answers, round lengths to three significant digits and angles to the nearest tenth of a degree).B = 105.0°, b = 33.0 mi, a = 23.0 mi
A. A = 42.3°, C = 32.7°, c = 18.4 mi B. A = 42.3°, C = 32.7°, c = 12.9 mi C. A = 32.7°, C = 42.3°, c = 18.4 mi D. A = 32.7°, C = 42.3°, c = 12.9 mi E. No solution.
