20Sin(70)= 18.79385

OpenStudy (anonymous):

wait... that doesn't seem right

OpenStudy (anonymous):

testingtutor, could you double check that?

20 cosec 70° ?

OpenStudy (anonymous):

ya, i think that is it

OpenStudy (anonymous):

and turing...

OpenStudy (zepp):

The length 'opposite' is 20, what we are looking for is the hypotenuse

OpenStudy (anonymous):

I was not trying to break the CoC, I thought I had explained it....

OpenStudy (zepp):

And we know that's a sine. \[\sin70 = \frac{20}{Hypotenuse}\]

OpenStudy (zepp):

Hence, \[Hypotenuse = \frac{20}{sin70}\]
