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

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

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !
