Answer:
6.3 ft.
Step-by-step explanation:
This requires the pythagorean theorem: a^2+b^2=c^2 where "a" and "b" are legs and c is the hypotenuse(longest side of the triangle which is opposite to the 90 degree angle.) If we fill the equation where c is the ladder length(11) and "a" is the distance from the house(), and "b" is the height, 9^2+b^2=11^2 or 81+b^2=121. This is equivalent to b^2=40. b=6.3 when rounded to the nearest tenth.
Based on the data given, the length of line segment AC is 2.29
<h3>What is the length of side AC?</h3>
Based on the given data:
- AC=BC
- AB=3
- line segment CD is perpendicular to line segment AB
- CD= sqrt 3
The triangle ABC is an isosceles triangle.
The line segment AC is the hypotenuse of the the triangle ACD.
The length of AD = 3/2

In conclusion, the length of AC is 2.29
