thanks i have no idea how to do this

Answer 3

Sorry don't know how to do this...but @Luigi0210 might

Answer 5

I think you have to use \(\Large a^2+b^2=c^2 \) right?

Answer 6

i think so

Answer 7

Hmm, okay, I'mma try and see if I can solve it since Gane isn't here yet >.<

So what I would do is use \(a^2+b^2=c^2 \)
Since we have the diameter as 16, we can get the radius by cutting it in half and use that as the hypotenuse: \( a^2+b^2=8^2 \)
That 6.5 could be used as one of the sides of the triangle: \( 6.5^2+b^2=8^2 \)

So we have this triangle:


So just solve this equation for b and you should get x:

\(\Large \color{green}{6.5^2+b^2=8^2} \)

Do you have any answer choices?
