Two pole of heights 6m and 11m stand on a plane ground. If the distance between their feet is 12m, determine the distance the distance between their poles.

1. Steve

Draw a diagram. If you draw a horizontal line from the top of the 6m pole to where in intersects the 11m pole, then you have a right triangle with legs 5 and 12.

You should be able to recognize the ubiquitous 5-12-13 triangle. The tops are 13m apart.
