Question

Two friends are on opposite sides of a river. To find the width of the river, each of them hammered a stake on his bank of the river in such a way that the distance between the two stakes approximates the width of the river. One of the friends walks 130 feet away from his stake along the river and finds that the line of sight from his new position to his friend's stake across the river and the line of sight to his own stake form a 35° angle. How wide is the river? The river is about feet wide. (Do not round until the final answer. Then round to two decimal places as needed.)
