cases where the distance being measured is not a direct line of sight from a point perpendicularly across the landmark, it is still possible to find the distance across the river with a line of sight at 45°45° and 30°30°, or at 60°60° and 45°45° with respect to the landmark. Observer 1 measures an angle of 45°45° with respect to the river, and observer 2 measures an angle of 30°30° with respect to the river. If the distance between observer 1 and observer 2 is 198198 meters, what is the distance across the river to the nearest tenth?

Question
In cases where the distance being measured is not a direct line of sight from a point perpendicularly across the landmark, it is still possible to find the distance across the river with a line of sight at 45°45° and 30°30°, or at 60°60° and 45°45° with respect to the landmark.
Observer 1 measures an angle of 45°45° with respect to the river, and observer 2 measures an angle of 30°30° with respect to the river. If the distance between observer 1 and observer 2 is 198198 meters, what is the distance across the river to the nearest tenth?
