Answer:
Step-by-step explanation:
Please refer to attachment for figure of the problem.
From the figure, we can see that window, ladder and ground forms a right angled triangle. hence, applying Pythogoras theorem in ΔWXY
We get,
WY² = WX² + XY²
From the question
WX = 60 ft
XY = 11 ft
WY = ?
Substituting the values in the above expression:
WY² = 60² + 11²
= 3600 + 121
= 3721
WY = √3721
= 61
Hence, length of the ladder = 61 feet
