2. A surveyor has estimated that a mountain is 2540 ft high. He also measures the angles of depression (from the top of the mountain to two observation stations on the ground) are 40° and 35°, respectively. Assume that the angle between the lines of the top of the mountain to the stations is 84°. Based on the information given above, (a) Sketch a graph, (b) Calculate the distance between the two observation stations.
