Two fire-lookout stations are 10 miles apart, with station B directly east of station A. Both stations spot a fire. The bearing of the fire from station A is N25E and the bearing of the fire from station B is N56W. How far, to the nearest tenth of a mile, is the fire from each lookout station?
So I got side a = 4.28 b=8.4 and angle C 180 - (25+56) = 99
But the books says the station A is 6 miles and station B about 9 miles from fire?
Where exactly did i mess up?
