Please help, i will give u brainliest

A

Step-by-step explanation:

First, lets see how to get BC.

First, let us do the tangent of 55. Finding the tangent will give us 7/BC. All we have to do to get the 7 out is divide by 7.

Luckily, we got the answer this time. But in the near future, it might be harder!

Hope this helped!

i think this could be a possible answer (1 / 84) -1

good luck! : d
