To find the missing length (?), we use the principle of similar triangles, which states that the ratios of corresponding sides are equal.

Given:

• Larger triangle's vertical height: $36$
• Smaller triangle's vertical height: $20$
• Larger triangle's base segment: $25$
• Smaller triangle's base segment: $?$

Solution:

The ratio of the heights gives the ratio of the bases: $\frac{\text{Height of smaller triangle}}{\text{Height of larger triangle}} = \frac{\text{Base of smaller triangle}}{\text{Base of larger triangle}}$

Substitute the known values: $\frac{20}{36} = \frac{?}{25}$

Simplify: $\frac{5}{9} = \frac{?}{25}$

Cross-multiply: $9 \cdot ? = 5 \cdot 25$

Solve for $?$: $? = \frac{125}{9} \approx 13.89$

Final Answer:

The missing length is approximately 13.89 units.
