Answer:
The ladder leaning against the wall forms a right triangle. The hypotenuse is the slanted ladder (13). The distance from the wall is the bottom of the triangle (6) and the height the ladder touches the wall is what we are trying to find out. Use the Pythagorean theorem a^2+b^2=c^2
So 6^2 + h^2= 13^2; h^2+36=169; h^2=133 h= square root of 133 or 11.5
