I know the law of sines, and before I can find b, i need to find the angle c. so right now I have 13sinx=19sin40

work out angle C first, and do it yourself that will give you angle B. you sais: "13sinx=19sin40" you called it x. call it C, be consistent with the diagram so 13sinC=19sin40 C = ..... B = .....
BloomLocke367
  • BloomLocke367
how do I work it out from there? that's why I'm stuck @IrishBoy123
BloomLocke367
  • BloomLocke367

@amistre64
IrishBoy123
  • IrishBoy123
what is angle C? you can work that out
BloomLocke367
  • BloomLocke367
right now I have sinC=19sin40/13. what do I do next?
IrishBoy123
  • IrishBoy123
use you calculator
IrishBoy123
  • IrishBoy123
use you"r" calculator
BloomLocke367
  • BloomLocke367
all I have is a scientific calculator
IrishBoy123
  • IrishBoy123
that's more than you need .... in terms of hardware arcsin (19sin40/13) = 70 -ish does that help?!
BloomLocke367
  • BloomLocke367
ohhh.. my calculator doesn't have arcsin. that was my problem
IrishBoy123
  • IrishBoy123
buy one that does :p lol!!
IrishBoy123
  • IrishBoy123
so what is B? does your scientific calculator have "+" and "-" buttons ?!?!
BloomLocke367
  • BloomLocke367
XD okay. so then I have a and c, they add up to 110. 180-110=70 so angle b is 70, right?
BloomLocke367
  • BloomLocke367
yes, hahaha
IrishBoy123
  • IrishBoy123
sounds about right!!
BloomLocke367
  • BloomLocke367
