Working with Laws and of Sines and Cosines.
Two observers are standing on shore 1/2 mile apart at points A and B and measure the angle to a sailboat at a point C at the same time. Angle A is 63 degrees and angle B is 56 degrees. Find the distance from each observer to the sailboat.

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 the distances from each observer to the sailboat.
