A ladder on the platform of a firebrigade van can be elevated at an angel of `70^(@)` to the maximum. The length of the ladder can be extended upto `20m`.If the platform is `2m` above the ground, find the maximum height from the ground upto which the ladder can reach `(sin 70^(@)=0.94)`

Text Solution

Verified by Experts

The correct Answer is:

Other end of the ladder can reach 20.80 m above the ground ladder.
