Is this a Law of Sines problem for a given triangle or something else? I did not see a diagram.

Are you saying there is no triangle diagram to go with this?
kymber
  • kymber
There was no diagram. Want me to draw one.. ?
Directrix
  • Directrix
No. I drew one. I was concerned that this might be the ambiguous case. Hold on. I'll crank out the problem and compare to your work.

sin(62)/a = sin(39)/15 sin(62) = (sin(39)/15)*a 15*sin(62) = a*sin(39) (15*sin(62))/sin(39) = a a = (15*sin(62))/sin(39) a = (15*0.88294759285892)/(0.62932039104983) a = (13.2442138928838)/(0.62932039104983) a = 21.0452641949038 Now round to the nearest whole number to get a = 21 So the answer is choice A (oddly enough...)

@kymber --> I think you got lost in the computation. Suggestion: spread out your work and try not to lose the variables. :) Just saying.
