OpenStudy (anonymous):

the hypotenuse=? (You tell me)

OpenStudy (anonymous):

\[HINT:~~~~~a^2+b^2=c^2\]

OpenStudy (anonymous):

25+36 = 61

OpenStudy (anonymous):

yep, so it's\[\sqrt{61}\]

OpenStudy (anonymous):

Now, Cos=Adj/Hyp Sin=Opp/Hyp therefore Csc=Hyp/Opp

OpenStudy (anonymous):

SOHCAHTOA

OpenStudy (anonymous):

cos = 6/sqrt61 ?

OpenStudy (anonymous):

Apparently yes, right?

OpenStudy (anonymous):

Agree, and csc=?

OpenStudy (anonymous):

csc = sqrt61/5 ?

OpenStudy (anonymous):

Over -5

OpenStudy (anonymous):

so its -5/sqrt61

OpenStudy (anonymous):

Yes, for csc

OpenStudy (anonymous):

No

OpenStudy (anonymous):

Sorry

OpenStudy (anonymous):

?

OpenStudy (anonymous):

Csc=sqrt61/-5

OpenStudy (anonymous):

there

OpenStudy (anonymous):

it says that they are incorrect

OpenStudy (anonymous):

I am sorry then.

OpenStudy (anonymous):

its ok

OpenStudy (anonymous):

Well id think so, unless you got the rest right.

OpenStudy (anonymous):

cos was 5sqt61 / 61 and csc was -sqr61/6

OpenStudy (anonymous):

yeah sorry again.
