Given that: A = 63 B = 56 C = 61 (since these angles should be equal to 180)
a = b = c = 1/2
sin 63 / a = sin 61 / .5 a = .51 miles
sin 56 / b = sin 61 / .5 b = .47 miles
The correct answers are: 0.51 miles and 0.47 miles. These are <span>the distances from each observer to the sailboat. </span> Thank you for posting your question. I hope that this answer helped you. Let me know if you need more help.
