Step 1 :Let A be the Albacore's position, B be the Bonito's position, and D be the distress flare's position. Let AD be the distance from the Albacore to the distress flare, and BD be the distance from the Bonito to the distress flare.
Step 2 :We know the angle ABD is 45 degrees, and the distance AB is 50 km. We also know the angles BAD and ADB, which are 5 degrees and 50 degrees, respectively.
Step 3 :Using the Law of Cosines, we can find the distances AD and BD:
Step 4 :\[AD = \sqrt{AB^2 + BD^2 - 2(AB)(BD)\cos{\angle ABD}}\]
Step 5 :\[BD = \sqrt{AB^2 + AD^2 - 2(AB)(AD)\cos{\angle BAD}}\]
Step 6 :Plugging in the known values, we get:
Step 7 :\[AD = \sqrt{50^2 + BD^2 - 2(50)(BD)\cos{45^\circ}}\]
Step 8 :\[BD = \sqrt{50^2 + AD^2 - 2(50)(AD)\cos{5^\circ}}\]
Step 9 :Solving for AD and BD, we find:
Step 10 :\[AD \approx 34.20 \mathrm{~km}\]
Step 11 :\[BD \approx 73.73 \mathrm{~km}\]
Step 12 :\(\boxed{\text{The Albacore is approximately 34.20 km away from the distress flare, and the Bonito is approximately 73.73 km away from the distress flare.}}\)
