Transcribed Image Text:### Task: Find \( x \) so that the triangles are similar.
We have two triangles in the diagram:
#### Triangle \( LMN \)
- Angle \( L \) = 43°
- Angle \( M \) = 49°
- Angle \( N \) = 88°
- Side \( LM = 52 \)
- Side \( MN = 40 \)
- Side \( LN = x \)
#### Triangle \( PQR \)
- Angle \( P \) = 43°
- Angle \( Q \) = 88°
- Angle \( R \) = 49°
- Side \( PR = 30 \)
- Side \( PQ = 42 \)
- Side \( QR = 30 \)
### Instructions
To make the triangles similar, their corresponding angles must be equal and the sides must be proportional. Therefore, you can set a proportion between the corresponding sides and solve for \( x \).
#### User Input
There is a field provided for entering the value of \( x \).
### Next Steps
Once you find \( x \), select "Next Question" to continue practicing similar triangles.
