, and that to the other is 
. How far apart are the cars?
above the ground, wants to determine the distance between two landmarks on the ground below. She observe that the angle formed by the lines of sight to these two landmarks is 
. She also observe that the angle between the vertical and the line of sight to one of the landmarks is 
and that to the other landmark is 
. Find the distance between the two landmarks.
