Answer:
Step-by-step explanation:
You have to use the sine law
Start by finding < B
<B + 58 + 93 = 180 Combine
<B + 151 = 180 Subtract 151 from both sides.
<B = 29
Now set up the sine law ratios
Sin (93) / BC = Sin (29) / 16
Sin(93) = 0.999
Sin(29) = 0.485
Now put these values into the Sin law found above.
0.999 / BC = 0.485 / 16 Cross Multiply
BC*0.485 = 16*0.999 Combine
BC *0.485 = 15.984 Divide by 0.485
BC = 15.984/0.485
BC = 32.857
