Answer:

20ft

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.

12^(2) +16^(2) = x^(2)

144+ 256=
x^(2)

x^(2) = 400

$x=√(400) \\x= 20$

Hence the length of the stick is 20ft.

Hope this helps.
