Are you assuming the buoy is at sea level?

anonymous · Answer

Think: TOA

ummm i just tried to calculate it by myself and i got 238ft?

anonymous · Answer

Would you like to get a textbook, so we can work from the same text? It's free.

ttop0816 · Answer

i would like to but im kind of in a hurry right now): so is my answer correct?

anonymous · Answer

Yeah, that sounds right to me.

anonymous · Answer

I don't know. I'm studying this stuff myself. Or at least TRYING to find people to study with. But if you've got to go.

anonymous · Answer

Does anybody on here want to actually STUDY?

anonymous · Answer

Why is it incorrect?

anonymous · Answer

Maybe we could, like, study Trigonometry? Could you go in for that? Might be fun.

ranga · Answer

I am getting the same answer you got.

anonymous · Answer

How'd you get it?

ranga · Answer

96 / tan(22)

anonymous · Answer

@DonaldRoyMiller -- I don't need to study, but if you have any Trig questions I'd be glad to help.

anonymous · Answer

Yeah, that's definitely the answer.

anonymous · Answer

I'm mostly interested in studying, but I'll look you up if I can't find anyone to study with. Check this out. It's good if you want to have a common textbook to work from with someone. http://opencoursescholar.wordpress.com/resources/openstax-textbooks/ In this case you would go to trigonometry and click on that, but all those titles are free.

anonymous · Answer

237.61 feet, right?

anonymous · Answer

yeah, but the question wanted you to round to the nearest whole number

anonymous · Answer

Or would it be at three decimal places, since that's one of the options (answers)?

anonymous · Answer

Oh, didn't catch that. Got sidetracked on the other stuff.

nincompoop · Answer

do you know how to round off?

anonymous · Answer

I'm a little fuzzy on it. But I know where to look. I have the textbooks. Did you catch that link I placed on here?
