Question 206710: Solve the problem.
By holding a ruler 3 feet in front of her eyes as illustrated in the diagram, Carla sees that the top and bottom points of a vertical cliff face line up with marks separated by 4" on the ruler. According to the map, Carla is about a half mile from the cliff. What is the approximate height of the cliff rounded to the nearest foot? Recall that a mile is 5280 feet.
(I dont know if this problem is solvable without the pictue, but it is basically Carla viewing the mountain from a particulat distance)
