Answer:
A: 53.68
Step-by-step explanation:
To find the length of BC use the tangent formula because that's the only one that makes sense.
To solve this though, write this
Tan 54 = x/39
Put 39 on the other side
39 tan 54
Then put parenthesis around 54
39 tan(54)
Now use your calculator and type in 39 tan(54)
As your final answer, you will get 53.68
So the length of BC is 53.68.
