Use the Law of Sines to find BC.
Round your answer to the nearest tenths.
B
20
35°
50°
C

Answer:
Step-by-step explanation:
law of sines is : Sin(A) / a = Sin(C) / c
where A=35
a = BC
C=50
c=20
Sin(35) / a = Sin(50) / 20
0.5735764 / a = 0.76604444 / 20
0.5735764 / a = 0.03830222
0.5735764 / 0.03830222 = a
14.975 = a
BC = 15.0
