Question

4. Two poles of heights 6 m and 11 m stand on a plane ground. If the distance between
their feet is 12 m, find the distance between their tops.​

Answer 1

Answer:

Step-by-step explanation:

• The distance between the poles is 12m
• Height of one pole is 6m and other is 11m

• Consider a rectangle and a triangle, in which the triangle is on top of rectangle.

      The length of the rectangle is the distance between their feets and the breadth the height of small pole.  The base of triangle is also 12m and the remaining portion of large pole ( 11-6=5 ) is 5m

Here we get a right triangle with base 12m, height 5m and hypotenuse as the distance between the poles.

then,

hypotenuse² = base²+height²

                     = 12²+5²

                     = 144+25

                     = 169

 hypotenuse  = √169

                     = 13m

ie, the distance between the tops is 13m..

Answer 2

Answer:

The distance between the tops is 13m
