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 = 102 m along the riverbank to establish a baseline. Then he sights across to the tree. The angle from his baseline to the tree is ? = 30.8°. How wide is the river?
