Answer:
The length of the mid-segment of the trapezoid = 7
==================================================
Step-by-step explanation:
The mid-segment of a trapezoid is the segment that connecting the midpoints of the two non-parallel sides.
As shown in the figure the two non-parallel sides are AB and CD
∴ The mid-segment of the trapezoid = 
From the figure: BC = 8 and AD = 6
∴ The mid-segment of the trapezoid = 
If angle AEC is 90° and angle AEB bisects it and is 45° that right there proves that angle AEB bisects angle AEC
14x13= 182 sq ft
183 sq ft = 20.22 sq yd
28.95x20.22=
5853690
move the decimal four spaces from the right and round up
585.37 is the answer
