text: wanna slove a hard trig question? in a national park, two fire stations are located 10 km apart. a fire is located at an angle of 47º mesaured at station a and at an angle of 62º messured at station b. how far is the fire from each station? use law of sines: a/sina = b/sinb = c/sinc  c=10, c = 180-47-62=71  c/sinc = 10/sin71  a = (10/sin71)sina  = (10/sin71)sin47  b = (10/sin71)sinb  = (10/sin71)sin62
