Answer:
9 m
Step-by-step explanation:
Suppose AB is the ladder. AC is the height of the window above the ground and BC is the distance of the foot of ladder from the wall.
The triangle ABC is right angled at C.
∴ AB² = AC² + BC²
=> 15² = 12² + x²
=> 225 - 144= x²
=> 81 = x²
=> 9 = x
- Hence, distance of the foot of the ladder from the wall is 9 m.
Answer:
Step-by-step explanation:
To solve this problem, first you have to isolate it on one side of the equation.
First, switch sides.
x/4=13
Next, multiply 4 from both sides.
4x/4=13*4
Then, solve.
13*4=52
Therefore, the correct answer is x=52.
