Answer:
20ft
Step-by-step explanation:
Height from the ground=16ft
distance from wall= 12ft
length of the stick=?
According to the Pythagoras theorem the square of the hypotenuse is equal to the sum of the squares of the opposite sides.
Here the stick is the hypotenuse.
[tex]12^{2} +16^{2} = x^{2}[/tex]
144+ 256= [tex]x^{2}[/tex]
[tex]x^{2}[/tex]= 400
[tex]x=\sqrt{400} \\x= 20[/tex]
Hence the length of the stick is 20ft.
Hope this helps.
