0°. Rangers at fire tower A spots a fire at 42°, and rangers at fire tower B spot the same fire

at 64°. How far from tower A is the fire to the nearest tenth of a mile?

- Trigonometry (Law of Sine) -
**Reiny**, Saturday, February 25, 2012 at 9:19amYour wording of the question is confusing, but I think I see a triangel FAB, where AB = 10

angle A = 42° and angle B = 64°

then angle F = 180-64-42 = 74°

FA/sin64 = 10/sin74

FA = 10sin64/sin74 = appr 9.4 miles
