have you learned soh cah toa?

anonymous · Answer

heard of it but havent learned it

anonymous · Answer

sin: Opposite/Hypotenuse
cos:Adjacent/Hypotenuse
tan:Opposite/Adjacent

anonymous · Answer

yeah

anonymous · Answer

i have trouble figuring out which is for which side ;[

anonymous · Answer

for your options is it tan25=x/30, tan30/x etc. or what? they look weird

anonymous · Answer

yeah

anonymous · Answer

ok. when you do either sin, cos, or tan the hypotenuse is always the hypotenuse. it's never the adjacent or opposite.

anonymous · Answer

so in this case your answer is sin25=x/30

anonymous · Answer

i have another question like this i just dont know which is hypotenuse, adjacent, and opposite

anonymous · Answer

go ahead
