Please help, math homework problem.?

I need help w/this prob.





You are on a trip to one of the cartesian islands. In the cellar of your cabin you have found an old map that claims to hold the secret location of buried treasure. The map shows four trees at location A, B, C, %26amp; D. The trees A %26amp; D are along an east-west road running through island. The tree at B is directly north of the tree at A, and the tree at C is directly north of the tree at D.





The maps directions say to trace a path from the tree at B to the tree at D, and to do the same for the trees at A and C. The treasure is buried halfwy between the intersection of these paths (point E) %26amp; the road. Because 3 small lakes dot the island, you r only able to measure the distances between B and D, A and C, %26amp; A%26amp;D:





B to D=300 paces


A to C=260 paces


A to D=240 paces





To find the location of th treasure you must find the distance from E to teh road %26amp; then walk 1/2 that distance from E. How far is E from the road %26amp; how far is is E from the buried treasure?

Please help, math homework problem.?
Draw extra lines, think outside the box as to how you can make right triangles. Use the numbers provided and draw a graph as close to scale as you can (In other words, make sure the dist from A to D looks longer than the dist from A to B. This will help you visualize. Then draw lines that can help you form right triangles (especially those that have two know lengths) use the pythagorean theorum and that should give you some help. Start by extending the D to C line further north until it is exactly east of point B. This new point we'll call F. Now you can figure out B to C because you know C to F is exactly 80. (A to B minus D to C) C to F is 80, B to F is 240 which makes B to C 253. It'll take some time, but you'll get it.
