Question

1. scale factor= ____ missing side length =____

Explanation:

Step1: Find Scale Factor

The scale factor is the ratio of corresponding sides. The base of the first triangle is 4, and the base of the second is 8. So scale factor $= \frac{8}{4} = 2$.

Step2: Find Missing Side Length

The corresponding side to \( x \) in the first triangle is 5. Multiply by scale factor: \( x = 5 \times 2 = 10 \).

Answer:

Scale Factor = 2, Missing Side length = 10
