A balloon moving in a straight line passes vertically above points A and B on a horizontal plane 1000 m apart. When above A it has an altitude of 600 as seen from B and when at B it has an altitude of 450 as seen from A. Find the distance from A of the point where the balloon will touch the ground.

Answer should be 2000 m ;
however thats my intuition... I feel the question still lacks something.

I believe that CEFB is a Square. Its clear that it is a parallelogram. and it is a rectangle.

I am sure there must be a better explanation., but to me this question is unclear or we will have to use things we never learnt(or learnt earlier)..

Lets recollect - "Given a right triangle , draw the altitude from the right angle . Then the triangles so formed are similar to each other as well as the right triangle." + if we use angle bisector theorem we are likely to get the result but these things haven't been taught.



NEway Best of Luck for Tomorrow.
