Question

About how long is the log that goes across the creeks?

Answer 1

6 feet

Explanation:

we know that

The triangles of the figure are similar by AA Similarity Theorem

Remember that

If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

Applying proportion

Let

x ----> the length of the log in feet

`(x)/(8)=(9)/(12)\\\\x=8(9)/12\\\\x=6\ ft`
