Question

@esshotwired Last question, I promise! Thanks! ^-^

Answer 1

you would have to use cos to find x. cos(60)= 8/x do you know what to do from here on?

Answer 2

No... I actually have no idea... .-. I'm really sorry.

Answer 3

cosine is adjacent over hypotenuse. one way to remember that is cos is CAH. "C" for cosine, "A" for adjacent, and "H" for hypotenuse.

Answer 4

ok so you would have to plug it in your calculator

Answer 5

you would write it like this: 8/ cos(60)

Answer 6

then that would be your answer

Answer 7

\[\cos(60)=\frac{ 8 }{ x }\]
You should probably use a calculator for this and just plug in the equation
