Molly and James are on the opposite sides of a river. To find the width of the river, each of them hammers a stake on his/her bank of the river on such a way that the distance between the two stakes approximates the width of the river. Molly walks 10 ft away from her stake along the river and finds that the line of sight from her new position to her stake from 73deg34' angle. How wide is the river?

Molly's line of sight would not be at an angle to her stake. Check to see if it should be to James' stake.
