Question 1194936: Solve the following practical application. Provide a systematic solution with
illustrations
A geodetic engineer wishes to find the distance across a river from point A to B. He finds that the distance from A to a point C on the same side of the river is 200 meters and the angles BAC and BCA are 59°23’ and 48°17’, respectively. Find the distance AB. Answer by Edwin McCravy(20055) (Show Source):
We will use the law of sines:
b = 200
sin(C) = sin(48o17') = 0.746444643
But we need angle B:
angle B = 180o - 59o23' - 48o17' = 72o20'
sin(B) = sin(72o20') = 0.9528381993
