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 0.16 km along the riverbank to establish a baseline. Then he sights across to the tree. The angle from his baseline to the tree is 37.7°. How wide is the river in ft?

Figure in plane geometry formed by two rays or lines that share a common endpoint, called the vertex. The angle is measured in degrees using a protractor. The different types of angles are acute, obtuse, right, straight, and reflex.
