Answer:

x = 30

Step-by-step explanation:

Angles on a line equal 180

4x + 20 + 40 = 180

4x + 60 = 180

Minus 60 on both sides.

4x = 120

Divide by 4 on both sides.

x = 30

Look at the figure below; what additional information do you need to have to determine if segment DE is the midsegment?

77julia77 [94]

1. If you knew that DE = $\frac{1}{2}$ CB
Then you would know it is a mid-segment.

2. If you knew that CD = DA and BE = EA (point D and point E are midpoints of their respective segments)
