Answer: 
Step-by-step explanation:
Since, In the given diagram,
The sides of the triangles ABC and EDC are,
BC = 62 feet, DC = 93 feet and DE = 125 feet(given)
And, angles B and D are right angles,
⇒ 
( Vertically opposite angles )
By AA similarity postulate,

The sides of similar triangles are in same proportion ,
⇒ 
⇒ 
⇒ 
By substituting the values,
We get,
⇒ 
⇒
