Math Problem Statement
Solution
The problem in the image involves a right triangle and the task is to determine the value of , the length of . The triangle has the following details:
- The segment is perpendicular to .
We can approach the problem using similar triangles. The larger triangle and the smaller triangle are similar since both share a right angle and have corresponding angles at . This similarity allows us to set up a proportion between the sides of the triangles.
Step-by-Step Solution
Let’s denote:
- (since and )
Since the triangles are similar:
We know that:
