design a pedestrian bridge across a river in the town park. They need to figure out how Surveying for a Bridge Priya and Jasmine are engineers who have been asked by the local government to long to make the bridge Engineers use a device called a theodolite to measure the angle between two points from a fixed position. They use this information to figure out the distance between locations that are too far away from each other to measure directly. Priya sets up the theodolite on one side of the river. Jasmine sets up two spots on the opposite side of the river that are 10 feet apart. Priya. Jasmine 10 feet Suppose that Priya and Jasmine are directly across the river from each other in the location they want to put the bridge. There is a right triangle formed by Priya's theodolite and the two spots Jasmine set up. Priya determines that the angle between the two spots Jasmine set up measures 20°. What is the distance across the river?
