Math Problem Statement
Solution
To solve for in this triangle problem, we can use the concept of similar triangles. Here’s the analysis step-by-step:
Step-by-Step Solution
-
Identify Similar Triangles: The two triangles and share the angle at . Also, they have pairs of corresponding sides that are proportional, making these triangles similar by the AA (Angle-Angle) criterion.
-
Set Up the Proportion: Since , we can set up the following proportion based on the sides:
-
Substitute Known Values: From the diagram:
- (Since we are given the full segment and is part of it)
Using these values, rewrite the proportion as:
-
Cross Multiply to Solve for : [ 5 \cdot PR = 12 \cdot
