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

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

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

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

    so, it has to be more than one line? LAST problem she asked I explaind why you would use sin and not cos ect.. gave her this link http://www.mathsisfun.com/sine-cosine-tangent.html and then solved it! She already had that info for this one...

    ^so that is why you need top check the askers understanding before providing the answer

    it's okay, just please try a little harder to make it so \(they\) give the correct answer, not you
