A surveyor measures the distance across a straight river by the following method: Starting directly across from a tree on the opposite bank, he walks x = 114 m along the riverbank to establish a baseline. Then he sights across to the tree. The angle from his baseline to the tree is θ = 36.8°. How wide is the river? y= ? An overhead view of a straight, horizontal river, with a tree on the upper-left bank. A point is marked on the lower right bank. The horizontal distance to the tree from the point is labeled x, and the vertical distance from the tree across to the opposite bank is labeled y. The angle between the horizontal lower bank and a line segment connecting the point and the tree is labeled θ.
