5-10.

The trapezoids below are similar shapes.

Refer to problem 4-98 for help with scale factors between two shapes.

1. What is the scale factor between shapes A and shape B?

What is the ratio between the pair of sides $50$m and $30$m?

2. Find the lengths of the missing sides.

Use this ratio with each other pair of sides with one given length to solve for the variable.

$x = 9$m
If $x$ is $9$m, what would $y$ be? Make sure to know how to get this answer.
