Draw the picture Fire Tower B 295o 45 miles 50o Tower A 329o
Find angle A, angle Band angle F. F B 65o 45 81o A Angle A 50o 329o 295o Angle B 50o Angle A = 360 – 329 + 50 Angle B = 295 – 180 – 50
Solve the triangle. F F = 180 – 81 – 65 34o BF = 79 miles B 65o 45 81o AF = 73 miles A The distance from tower A to the fire is 73 miles and from tower B to the fire is 79 miles.
