Question

Two poles of heights 6m and 11m stand on aplane ground,if thedistance between the feet of the poles os 12m find the distance between their topse

Answer 1

Answer:

DISTANCE BETWEEN TOPS = 13.42 m

Explanation:IF YOU CONSIDER THE TOP PART OF THE QUADRILATERAL, (FROM THE  TOP OF POLE B(6m)  TO THE POINT IN POLE A 6 m ABOVE THE GROUND) YOU GET AN EQUILATERAL TRIANGLE.

acc. to pythagoras theorem,

H^2=P^2 +B^2

H^2=(6)^2 +(12)^2

      =36+144

      =180

H=ROOT 180=13.42
