Question

Help I don’t know the answer

Answer 1

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.

$x = 128.4$
