Math Problem Statement
Solution
The image shows a triangle with two segments divided by a line, and the problem is to calculate the missing length, denoted as , with measurements in meters.
Given Information:
- The larger triangle has a height of 24 meters and a hypotenuse of 30 meters.
- The smaller triangle (inside the larger one) has a height of 18 meters.
- The two triangles are similar (indicated by the markings on the sides), meaning their sides are proportional.
Approach:
Since the triangles are similar, the ratio of corresponding sides will be equal. We can set up a proportion between the smaller and larger triangles.
For the height: For the hypotenuse (we are trying to find ):
Now, solve for :
Simplify to , and then cross-multiply:
Solve for :
Conclusion:
The missing length is 22.5 meters.
