Math Problem Statement
Solution
The image shows a square with one diagonal dividing it into two right triangles. The side lengths of the square are 12 meters, and additional dimensions are given for parts of the diagonal as 7 meters and 5 meters.
We need to determine the unknown dimension , which represents part of the diagonal.
To solve for :
- Use the Pythagorean theorem to relate the diagonal's parts.
- Recognize that the total diagonal forms from adding the 7 m, 5 m, and , making a complete diagonal across the square.
First, we calculate the total diagonal of the square using the formula for the diagonal of a square:
Now, we know that the sum of the parts along the diagonal is .
Thus, we solve for :
So, .
