Asurveyor has determined that a mountain is h = 2440 ft high. from the top of the mountain he measures the angles of depression to two landmarks at the base of the mountain and finds them to be 42° and c = 37°. (observe that these are the same as the angles of elevation from the landmarks as shown in the figure below.) the angle between the lines of sight to the landmarks is 68°. calculate the distance between the two landmarks. (round your answer to the nearest integer.)
