Question

Two poles of height 10m & 15 m stand vertically on a plane ground. If the distance between their feet is 53m then find the distance between their tops.\

Answer 1

Answer:

AB and CD are two poles with height 10m and 15m.

BD is the distance between their feet=53m

As poles are standing vertically, means they are making the angle of 90° with ground.

So, In triangle ACE

Angle E=90°

AE=53cm and CE=5cm

By pythaggoras,

H²=P²+B²

AC²=CE²+AE²

• AC²=5²+53²
• AC²=25+2809
• AC²=2834
• AC=under root 2834cm Ans.
