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.

9. A surveyor is mapping a large marsh in a state park. He walks and measures a straight line south from a cliff for 0.75 mile to a large tree. He walks east, but he has to make a detour around the marsh. He gets around the marsh to a spot where he is perpendicular to the large tree and the trail he originally walked south on. He looks northwest and measures a 40° angle (ZA) northwest to the cliff from his line of sight to the large tree. He measures the distance back to the starting point at the cliff as 1.17 miles. What is the straight-line distance from the large tree east to ZA? What is the tangent of ZB , the angle at the cliff? Clff 0.75 mile 1.17 mile 40 Tree
