Answer 
Find out the how high up the wall does the ladder reach .
To proof
let us assume that the height of the wall be x .
As given
 A 25-foot long ladder is propped against a wall at an angle of 18° .
as shown in the diagram given below
By using the trignometric identity

now
 
 
Base = wall height = x 
Hypotenuse = 25 foot
Put in the trignometric identity


x = 23.8 foot ( approx)
Therefore the height of the  ladder be 23.8 foot ( approx) .
