Provide an appropriate response.Use the law of sines to solve the triangle ABC if a = 18, b = 18, and A = 42°. If there are two possibilities, find both solutions. Round sides to four significant digits and angles to the nearest 0.1°.
A. no solution
B. B = 42.0°, C = 96.0°, c = 26.75; B = 138.0°, C = 42.0°, c = 18.00
C. B = 138.0°, C = 42.0°, c = 18.00
D. B = 42.0°, C = 96.0°, c = 26.75
