Angle C is unknown, but it can be determined. A+B+C = 180 50+107+C = 180 ... plug in the given angles, solve for C 157+C = 180 157+C-157 = 180-157 C = 23 Use the law of sines to find length 'a'. sin(A)/a = sin(C)/b sin(50)/a = sin(23)/8 a = ???
OpenStudy (kj4uts):
@jim_thompson5910 b/sin(107) = 8/sin(23) b = 19.58 The answer would be A. a=15.68 and b=19.58 right?
