Solve the triangle. For angles given in degrees and minutes, round to the nearest minute. Round all other angles to the nearest tenth of a degree when necessary. Round side lengths to the nearest hundredth when necessary.A = 65.3°a = 2.15 kmb = 2.25 km
A. B = 71.9°, C = 42.8°, c = 1.61 km B. B = 42.8°, C = 71.9°, c = 1.61 km or B = 6.6°, C = 108.1°, c = 0.27 km C. B = 71.9°, C = 42.8°, c = 1.61 km or B = 108.1°, C = 6.6°, c = 0.27 km D. No solution
