To find the distance between a tree and a boulder that lie on opposite banks of a river, Mia, a surveyor, lays off a line segment of length 240 yards along one bank between the tree and her car. She
determines that the angle from the tree to her car to the boulder is 54° 10'. Mia also determines that the
angle from her car to the tree to the boulder is 63° 20'. How far apart are the tree and boulder?
