Answer 2

Given :

• 2 poles of height 9m and 14m stand vertically on a plane ground.If the distance between their feet is 12m

To find :

• the distance between their tops

Solution :

AB = AD - CE ( CD = BD = 9)

AB = AD - BD

AB = 14 - 9

AB = 5 m

now,

ΔABC apply phythagoran theorem

AC² = AB² + BC²

AC² = 5² + 12²

AC² = 25 + 144

AC² = 169

AC = √169

AC = 13

∴ Top distance is 13 cm
