Math Problem Statement
Solution
The problem presents two similar triangles, where the smaller triangle is similar to the larger one. You are tasked with finding the value of by setting up a proportion.
Given the diagram in the image, we have:
- The smaller triangle has a side length of 8.
- The larger triangle has a side length of 10.
- The corresponding side length in the smaller triangle is , and the corresponding side in the larger triangle is 8.
To solve for , we can use the property of similar triangles, which states that corresponding sides are proportional. Therefore, the proportion can be set up as follows:
Now, solve for :
-
Cross-multiply:
-
Simplify:
-
Divide both sides by 10:
Thus, .
