Answer:
19.5 m
Step-by-step explanation:
The length of one pole is 15 m and the length of the another pole is 7.5 m.
The distance between them is 18 m.
Now consider the figure shown below:
BE = CD = 7.5 m
AE = BE + AB
15 = 7.5 + AB
AB = 7.5
BC = 18
Now calculate the value of AC by using Pythagoras theorem:
AB² + BC² = AC²
⇒ 7.5² + 18² = AC²
⇒ 380.25 = AC²
⇒ AC = 19.5
Therefore,
The length of a wire stretched form the top of one pole to the top of the other pole is 19.5 m.
Hope it helps!

ANSWER:
Your answer is 19.5 m
The length of one pole is 15 m and the length of the another pole is 7.5 m.
The distance between them is 18 m.
Now consider the figure shown below:
BE = CD = 7.5 m
AE = BE + AB
15 = 7.5 + AB
AB = 7.5
BC = 18
Now calculate the value of AC by using Pythagoras theorem:
AB² + BC² = AC²
⇒ 7.5² + 18² = AC²
⇒ 380.25 = AC²
⇒ AC = 19.5
Therefore,
The length of a wire stretched form the top of one pole to the top of the other pole is 19.5 m.
