Question

Help pls, thanks! :))))))

Answer 1

h= 13.6 ft

Explanation:

Let,

a= 8 ft

b= 11 ft

The ladder against the top of the house is creating a right triangle

So, we can find the length of the ladder using

pythagoras theorem...

`h^(2) = {a}^(2) + {b}^(2) \\ h^(2) = {8}^(2) + {11}^(2) \\ h^(2) = 64 + 121 \\ h = √(185) \\ = 13.6ft`

Therefore, the length of the ladder (h) = 13.6 ft ( rounded to the nearest tenth)
