Answer 2

Use either sine, cosine, or tangent, whichever you like.

Answer 3

I cannot remember how to use those.

Answer 4

you can use the sine law that says the (sineA)/a = (SineB)/b = (sineC)/c

Answer 5

Sorry I am very rusty with geometry. Just started geometry 2 so I'm trying to catch up. So how do I use sine to find B?

Answer 6

You can find them all on google but

sine = opposite/hypotenuse

cosine = adjacent/hypotenuse

Tangent = opposite/adjacent
