Answer 2

Answer:So, the answer for this question is that height of the wall is 8.48 feet.

Step-by-step explanation:

To calculate the height of the wall we need to follow these steps-

we will name the wall AC and ladder will be AB now we can say that distance between wall and bottom of ladder will be BC.

so it is given that AB is 11 feet BC is 7 feet , and we need to find AC which is height of wall.

According to question, equation will be,

AB²=BC²+AC²

11²=7²+AC²

121=49+AC²

AC²=121-49

AC²=72

AC=√72

AC=8.48

Therefore height of the wall is 8.48feet.
