what trig function you think you should use with the given info (angle A, hypotenuse)?

anonymous · Answer

and you want BC... that's opposite the given angle [HINT]

anonymous · Answer

I think its the first answer choice? But I have a feeling I'm completely wrong xD These questions always confuse me.

anonymous · Answer

you can use sin35 = opp/hyp = opp/8
so
sin35=opposite/8     (opposite side is BC)

can you solve for the opposite side in this equation:

sin35 = opp/8  [HINT: multiply both sides by 8]
