Answer:
See below.
Step-by-step explanation:
I'm assuming these questions are about the Midline Theorem (segment AL joins the midpoints of the non-parallel sides.
♦ The midline's length is the average of the lengths of the top and bottom parallel sides.

Use this equation and substitute values given in each problem, then solve for the missing information.
1. AL = x, CE = 9, OR = 5

2. AL = <em>m</em> - 4, CE = 15, OR = 17

3. OR = y + 5, AL = 15, CE = 18

First answer is correct.
