anyone? :(

psymon · Answer

Your answers make no sense xD Sin of one angle is the same as cosine of the other angle. But sin of x is 6/10. SO why all your options have a division of 8 Im not sure.

Thats what i'm saying!! -.-

psymon · Answer

Well, your question answers are wrong then xD The question made a mistake. But yeah, sin of one angle is the cosine of the other angle. So if you have to pick an answer, then youd pick the 6/8 identical one. Although its wrong :/

I picked that and i got it right!

psymon · Answer

Yeah, the question made a mistake. Just know the question is wrong and that the real answer is 6/10, 6/10 and that theyre identical.
