Help I don’t know the answer

Mathematics
1 answer:
labwork [276]3 years ago
7 0

Answer:

128.4 units.

Step-by-step explanation:

We need to set up ratios to do this problem.

Because both trapezoids are similar, we know that all corresponding sides are similar.

\frac{42}{35} = \frac{x}{107}

Simplify.

4,494 = 35x

Divide both sides by 35.

x = 128.4
