=A=

Find m∠C

m∠C = 180° - (51° + 71°) = 58°

Find the missing sides using the law of sines:

9.8 / sin 71° = AB / sin 58° = AC / sin 51°AB = 9.8 sin 58° / sin 71° =  8.8 cmAC = 9.8 sin 51° / sin 71° = 8.1 cm

=B=

Find m∠L

m∠L = 180° - (42° + 84°) = 54°

Find the missing sides using the law of sines:

50 / sin 84° = KL / sin 42° = JK / sin 54°KL = 50 sin 42 °/ sin 84° =  33.6 cmJK = 50 sin 54° / sin 84° = 40.7 cm

=C=

Find m∠R using the law of sines:

17.5 / sin 98° = 15 / sin ∠Rsin ∠R = 15 sin 98° / 17.5sin ∠R = 0.85m∠R = arcsin (0.85) = 58.2°

Find the missing angle:

m∠S = 180° - (98° + 58.2°) = 23.8°

Find the length of QR, use the law of sines:

17.5 / sin 98° = QR / sin 23.8°QR = 17.5 sin 23.8° /sin 98° = 7.1 m

< i think this is the answer unless i did my math wrong
