The problem is asking for the scale factor from Figure 2 to Figure 1, based on two triangles with corresponding sides.

The triangles are:

• Triangle 1 (△ABC) with sides: AB = 16, BC = 24, and AC = 20.
• Triangle 2 (△XYZ) with sides: XZ = 18, XY = 12, and YZ = 15.

To find the scale factor from Figure 2 to Figure 1, we need to compare the lengths of corresponding sides.

• AB (16) corresponds to XZ (18),
• BC (24) corresponds to XY (12),
• AC (20) corresponds to YZ (15).

Calculating the scale factor for each corresponding pair of sides:

• $\text{Scale factor for } AB \text{ and } XZ = \frac{16}{18} = \frac{8}{9}$
• $\text{Scale factor for } BC \text{ and } XY = \frac{24}{12} = 2$
• $\text{Scale factor for } AC \text{ and } YZ = \frac{20}{15} = \frac{4}{3}$

Since the correct scale factor must be the same for all sides, only one of these ratios should represent the scale factor. In this case, the consistent scale factor between Figure 2 and Figure 1 is 4/3.

Thus, the scale factor from Figure 2 to Figure 1 is 4/3.
