Answer:
Step-by-step explanation:
In the given triangle AED,
Points B and D are the midpoints of sides AD and AE.
a). Therefore, AB = [tex]\frac{1}{2}(AD)[/tex]
AB = [tex]\frac{90}{2}[/tex] = 45 ft
b). AE = 2(AC)
AE = 2(30)
AE = 60 ft
c). By mid-segment theorem,
BC = [tex]\frac{1}{2}(DE)[/tex]
BC = [tex]\frac{50}{2}=25[/tex] ft
d). EC = AC = 30 ft
