Question

Find the length of BC

Answer 1

A: 53.68

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.

Hope it helped! This answer is expert verified.
