Answer:

11.6feet

Step-by-step explanation:

1) The whole question set up will give a right angled triangle as shown;

Wea re to calculate the height of the wall. Using the pythagoras theorem;

Length of ladder = Hypotenuse = 12feet

Adjacent = 3feet

Height of the wall = opposite

Hyp^2 = Opp^2 + Adj^2

12^2 = Opp^2 + 3^2

144 = Opp^2 + 9

Opp^2 = 144-9

Opp^2 = 135

Opp = \sqrt[135]

Opp = 11.6feet

Hence the height above the ground that the ladder touches the wall is 11.6feet
