Question
The given pair is similar. Find X and Y
![### Understanding Triangle Proportions and Similarity
In the diagram provided, you will observe two triangles that appear to be similar. Triangle similarity means that the corresponding angles of both triangles are equal, and the lengths of corresponding sides are in proportion.
#### Diagram Details:
- **Left Triangle:**
- Side opposite to angle x is labeled as 1.8 units.
- Side opposite to the angle adjacent to x is labeled as 3 units.
- **Right Triangle:**
- Side opposite to angle y is labeled as 1.5 units.
- Side opposite to the angle adjacent to y is labeled as 1.2 units.
To determine if these triangles are truly similar, we analyze the ratios of the corresponding sides. If the ratios are equal, then the triangles are similar, and we can set up a proportion to find any missing side lengths or angles.
##### Example Calculation:
If the given sides of the triangles form a proportion, then:
\[
\frac{3}{1.5} = \frac{1.8}{1.2}
\]
Solving this will help to confirm the similarity of the triangles and to find the values of \( x \) and \( y \).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4bb5a6dd-97cd-4d93-a8e0-dafecb13cdf7%2F1e33a6d1-e3cc-4e43-83c1-4ade16c65bbc%2Fq67l43j_processed.jpeg&w=3840&q=75)
