Solve triangle ABC. Round side lengths and angle measures to the nearest tenth when necessary.b = 8, c = 9, A = 127°
A. a ? 21, B ? 22°, C ? 31° B. a ? 15.2, B ? 24°, C ? 29° C. a ? 18.1, B ? 26°, C ? 27° D. No triangle exists.
Without actually solving the equation, list all possible numbers that would have to be rejected if they appeared as potential solutions. Then give the domain using set notation.
