I do not know how to do this at all! :(

solomonzelman · Answer

cosine = adjacent / hypotenuse

anonymous · Answer

So is that 8/15 then?

anonymous · Answer

Please help step by step! :)

anonymous · Answer

Hoping angle at A is 90 deg, $$\ cos \theta = base /hypotenuse$$
base is AC and hyp. is BC.
Put the values and get the result.

solomonzelman · Answer

hypotenuse is the biggest side, not the one that's 15.

OH sorry to both! I really meant 8/17! @ShailKumar @SolomonZelman got this part! now what

solomonzelman · Answer

yes, 8/17 is right

anonymous · Answer

I can use the SOH CAH TOA method right? it helps!

solomonzelman · Answer

you found it :)

anonymous · Answer

So this is my answer? :O I just put 8/17 and it's correct?

solomonzelman · Answer

We did
$\normalsize\color{darkgreen}{ \rm  SOH   }$$\normalsize\color{red}{ \rm  CAH   }$$\normalsize\color{darkgreen}{ \rm  TOA   }$

$\normalsize\color{red}{ \rm Hyp = Adj~/~Hyp   }$

solomonzelman · Answer

yes 8/17
