Find the length of BC

Use tangent ratio (type in calculator)

Step-by-step explanation:

tan of 54 * 39 = 53.68

A

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.

i am currently in the exact same situation rn. algebra2/adv algebra is killing

step-by-step explanation:

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
