Provide an appropriate response. Use the law of sines to solve the triangle ABC if a = 11.8, b = 30.3, and A = 20.5°. If there are two possibilities, find both solutions. Round sides to four significant digits and angles to the nearest 0.1°.
A. c = 33.54, B = 64.1°, C = 95.4°; c = 23.24, B = 115.9°, C = 43.6° B. c = 33.54, B = 64.1°, C = 95.4° C. c = 23.24, B = 115.9°, C = 43.6° D. c = 15.99, B = 7.8°, C = 151.7°
