The length of the ladder nearest hundredth of a foot is 23 feet.
We have given that,
An electrician leans an extension ladder against the outside wall of a house so that it reaches an electric box 20 feet up.
The ladder makes an angle of
the ground.
<h3>
What is the sin ratio?</h3>
![sin(\theta)=\frac{perpendicular \ side}{hypotenous}](https://tex.z-dn.net/?f=sin%28%5Ctheta%29%3D%5Cfrac%7Bperpendicular%20%5C%20side%7D%7Bhypotenous%7D)
Therefore we get,
![\implies\frac{22}{H} =sin(77)](https://tex.z-dn.net/?f=%5Cimplies%5Cfrac%7B22%7D%7BH%7D%20%3Dsin%2877%29)
![\implies H=22/sin(77)](https://tex.z-dn.net/?f=%5Cimplies%20H%3D22%2Fsin%2877%29)
![\implies 22.59ft\\\\=23ft](https://tex.z-dn.net/?f=%5Cimplies%2022.59ft%5C%5C%5C%5C%3D23ft)
Therefore, The length of the ladder nearest hundredth of a foot is 23 feet.
