To find the missing side length in similar triangles ΔRST and ΔRQP, we need to use the property of similar triangles, which states that the ratios of the lengths of corresponding sides are equal.
Let's denote the sides of the triangles:
- If \( \frac{RS}{RQ} = \frac{ST}{QP} = \frac{RT}{RP} \), we can use the lengths of any pair of corresponding sides to find the missing side.
If you have specific lengths provided for certain sides of the triangles, please provide them so we can set up a proportion and solve for the missing side length.
