I'm required to figure out an angle for part of one of my physics questions. Got this so far:
Sin C / c = Sin B / b
Sin 40 / 27.83 = Sin B / 20
(0.6428) / 27.83 = Sin B / 20
(0.6428)(20) = (27.83)(Sin B)
12.586 = 27.83(Sin B)
[12.586 = 27.83(Sin B)] / 27.83
0.4620 = Sin B
I've gotten up to here so far. Though, I have no idea what to do next. Is 0.4620 my answer (angle of 46 degrees), or do I still have to do something with Sin B?
